    I have been collecting LFS movement serials numbers from eBay and other sources and I thought to share the attached spreadsheet with you. Additions and corrections are welcome.

    Serial number 74,965 movement is in an oak wall clock - time and 1/4 hour - plus hour strike - in a clock by George Goeser of Zurich

    It has a 43 on the side of the back plate - but I don't know what that means

    Hi all!

    I assume this movement was made in 1924.
    43 - the length of the pendulum in centimeters.

    Thank you so much - since posting I found an excel sheet that showed a lot of LFS serial numbers and the 74,xxx would fit into the 192x time frame.

    From the suspension spring pin to the center of gravity is 35 cm - and to the bottom of the rod is 50 - so the 43 would be a case size estimator - or perhaps it would be measured from somewhere below the pin :)

    This model is in the catalogue of 1929 under the number 3793.
    On the back wall of the case of this clock can stand the numbers 3793 and 128 (caliber movement).

    This excel table is too small to help in dating. A feature of the LFS is the numbering in accordance with the type of movement (movement caliber).

    Thank you so much - my customer will be very happy to hear all of this. His grandmother bought the clock in Zurich and he inherited it about 5 years ago when his mother died but did not know much about it. Sadly it has been abused a bit, but hopefully with some help I can get it back to normal for him.

    So Goeser of Zurich simply put his name on the dial of an LFS model clock? I know this was not uncommon.

    The parts LFS I found in Latvia (time and strike movement only) has serial 40557 - I am hoping to be able to get at least the tooth and leaf counts for the missing S3

    Thanks - it will be interesting to see if the single hammer S3 is the same as for the 6 hammer movement. Since both are 128 I am hopeful.
    There is a small lever on the 6 hammer model with a second cam that moves the two hammers for the 1/4 hour strike forward a bit so they do not strike on the hour. I am hoping that is the only real difference and would not matter to the design of the S3.

    This is another LFS - is a triple train - with 4 rods on the chime side and two on the strike
    It looks like model 129 on the back, but it is rather hard to read - also has a 7 in the middle of the back board
    Serial number is 115197
    It will need a bit of case work and a lot of movement work - but should be fun
    Any date or additional model information would be great
    thanks

    Greetings!
    The back plate of the movement shows 3 different patents issued during 1912-1913. So 1913 can be seen as "no early' date. Other than that there is a pencil writing on the back wall below the catalog / movement number. Is there any chance to make a better view of that? looks like a date?
    The upper number (374) should be a catalog No, while 129 refers to a works caliber. Will it be possible to get a front view of the movement? We have a clear front picture of the 129 caliber from the catalog, does it look the same as yours?
    Regards,
    Nick

    Thanks so much. When I return I will get more pictures and try some different lighting on the scripts. From other serials I had estimated mid 1920s. The movement is very dirty with some rust so removal of the dial was difficult. It should come off after a few days of penetrating oil.

    Looks a bit different - but similar - perhaps an newer version?

    As dirty as this is - it actually will function with finger pressure. The strike side initiation is different but still functions

    Interesting fan with moving counter weight -

    Curious cardboard tubes over the top two posts - Not sure why they are there. Nothing impacts the top posts. Must be some pretty good material to have lasted this long in such a dirty movement.

    This fan "fly" looks quite interesting although it is not something rare... Cardboard tubes also could be found on late LFS clockworks... Like here on the attached photo.

    Any idea what the purpose might be for the cardboard tubes? I was guessing that perhaps during assembly and testing they used the tubes to support the movement and not mar the posts and then simply left them in place.

    What would be the caliber number for this LFS - serial number 240 ?

    It is time and strike with a count wheel between the plates. I think the age is early 1880s ?

    What sort of case might it have been in? Any other information would be great as well.

    Looks like 116, but with some differences (maybe a modification of 116?). Do you have a picture of the case of the clock? May help to date. 116s are quite rare and it looks like they all come from 191x. Here is an example:

    Thanks. Unfortunately I know nothing about what this came out of. I got a batch of clock movements from a closed clock shop in Austria and this was in the mix.

    But to tell you the truth I have never seen LFS movement with internal count wheel. 116th caliber has normal rack and strike mechanics so this one you have showed us is really something rare and special!
    Maybe Tatyana has something similar in her database. If not, I am sure she will keep an eye on that matter.

    I came by this rather by accident and if it is indeed a bit rare and special it should go to someone who could put it to proper use, even if that means just to fully research and document the movement.
    It appears complete except for the hammer arm and I can see no other obvious damage.
    No matter how I tried to use it, I am not in a position to appropriately use an unusual movement.

    I don't have the experience, skills or resources to recreate what this probably came out of, and if it is rare it should be used accordingly.

    --------------------------------------------
    This movement from Latvia arrived yesterday and I am a bit puzzled.
    The plates on this movement (40557) are 30mm apart - which I assume is the 128 caliber standard size.
    The plates on the 74965 (customer's) movement are 38mm apart.
    The main reason for the difference is the size of the strike spring. The time spring barrels are the same, but the strike barrel on the 74965 is wider - hence the wider plates - and it is also larger diameter. I guess they needed a much larger spring to drive the opposing 4 and 2 hammer set up.
    There are no visible marks anywhere on the case of the customer's clock, because it has been re-varnished or lacquered at some point, so nothing shows.
    The S3 on 40557 and on the LFS 240 movement have 10 pins for the hammers, so I will assume that is correct for the 74965 as well.

    Hi THTanner,
    could you please show picture of 74965 movement from the rear, from the front and from the above. I just took a closer look at the pix you have provided (which do not show complete movement, just parts of it) and I am afraid your movement is not 128 cal. Besides you have mentioned it strikes 1/4, and 128 cal movements strike only half hour and hour.
    40557 from Latvia is no doubt 128 cal in its latter modification.

    I have been preparing a full set of pictures now that both movements are here. These are all of 74965. You will see the snail in front of the hour wheel for the rack as usual, and a second cam behind it. The one behind the hour wheel controls the 1/4 hour striking by the two hammer set. To the left of the snail are several levers that affect how the rack functions at the 1/4 1/2 and 3/4 and then also move the two hammer set out of the way for the hour strike by the four hammer set. In one photo you can see my thumb lifting the lever to move the two hammers toward the back plate about a 1/4 inch. S3 on this movement would most likely have 10 pins on one side for the hour strike hammers, and an unknown number of pins on the other side for the 1/4 hour action on the two hammers. With S3 missing I am not able to actually make everything go through a full cycle.

    The four hammers move as a group striking a four note chord. The two hammer pair are each activated separately like a bim-bam I have not been able to figure out if the hour hammer set also strikes the chord on the 1/4s. There does not appear to be anything that would keep the pins on that side from lifting the hour hammers. The owner has not heard any sound from the clock for more than 10 years and cannot remember what it actually sounds like, but he says he vaguely remembers that the 1/4s involve a multi note pattern, and the hour is the usual count out on a chord.

    The 128 caliber movement has 4 1/8 x 3 7/8 plates. 74965 plates are 4 7/16 square.

    the full set of photos takes three posts.

    fantastic. that is what I needed. Any chance of a closeup of S3? In particular I would like to know what the pin pattern is. Tooth and leaf counts would be great also. It looks like 6 pins for the bim bam, and the four hammer side with the pins straight through? Also what is the caliber number?

    ahhh - thanks so much for your help -
    by blowing up two of the images on a better screen I have been able to count 10 pins on S3 that go through the wheel for both sets of hammers. And I think 9 leaves, but that is by estimating from a 1/2 side view.

    In the you tube of the strikes - it sounds to me like at least one of the bim bam hammers, perhaps both, strike along with the hour count 4 chord hammers. I have not seen this in action, but moving things manually it seems that the hammer pair moves out of the way for the hour strike on this crippled movement. It certainly has a wonderful sound.

    Hello and thank you for having me here,

    I have inherited a wonderful LFS clock and I was wondering how old is it and if it's mechanism matches the case. The mechanism number is 16.460 and on the back of the case I guess 128 is written. I wanted to access the serial number list but it seems that I do not have enough posts in order to do that, so that's why I'm asking you this way. Thank you in advance.

    Kind regards,
    Angel H.

    The 128 is the "caliber" number of the movement indicating the type and size. The excel sheet that you cannot open indicates a date of about 1910 but others can perhaps get a bit closer. Can you post some pictures of the rest of the case and the dial?

    Your clock was made in 1912.
    Here is the same model from St. Petersburg.

    Thank you for the exact info. Do you happen to know if it's good mechanism? I really like the case mainly due to the fact that is made of rosewood, but also for it's elegant simplicity.

    Is the clock from the pictures yours? St. Petersburg brings up some nice memories for me...what a wonderful place.

    Kind regards,
    Angel H.

    I haven't unfortunately movements LFS, this 128 caliber was produced during 25 years.
    When sold this clock I thought it Lenzkirch, because on the dial is "Павелъ Буре" (this trading house specialized in sales Lenzkirch).
    This clock belongs to my colleague Sergey from the Russian forum.
    On the Russian forum a lot of information on LFS Датировка LFS - Часовой форум Watch.ru

    Greetings to everybody! A little input on 128 caliber and serial numbers. I got some pics of the clock with s/n 22 415, same clockworks, same trade house in Russia - Paul Bure (Павелъ Буре), although the case is something different. What is significant, the back deck of the case features a stamp with the year of manufacture (sale?). Please take a look. 1914 г stands for 1914 год (1914 year).
    BTW: I own several clocks with 128 movement and the only issue I had was in mainsprings. Some of them got tired and will not work for 14 days, so I am winding them weekly. Funny is that the later clocks made in 1930's mostly suffer from that.

    Tom, it looks like the caliber number of your clock is 112. I found these pix on net auction today:

    Early LFS with serial #7
    The case isn't complete and I am hoping for photos of a simular case.
    Thanks
