Please can anyone help with the identification of this Kundo clock. I bought it very cheap in an auction to practice on as I have never worked on one of these before. The suspension wire is broken and the bottom block is missing. I would like to buy a new one or better still the individual parts but I do not have the model number to determine which ones to buy.
Can anyone help identify the model from the images and if possible provide data on the positions of the bottom block and fork. I do not have access to the standard reference work on these clocks.
Any help would be greatly appreciated
Regards
Steve

This is a pre WWII Kundo clock without the base cup....likely before 1933. Looks like plate 1388A in the repair guide. Takes a 0.0032" suspension spring. The pendulum doesn't look right for the clock, though.

Suggest that a moderator move this to the 400-day forum area.

Yes, 0.0032" suspension spring would be right for this. What do you see amiss with the pendulum?

You won't get to far with a 400-Day clock without 'The Book'.

Any edition will be good.

You can buy the spring (0.0032") from suppliers such as Meadows & Passmore. Also the top and bottom blocks.

These clocks don't usally have a model name, they are identified by maker and the back plate (see post #2 above).

Not sure what you mean about the positions of the top and bottom blocks.

Michael posted that it looks like a Kern pendulum and I tend to agree. This is one style of pendulum that might have been used at the time.

Yes, having looked more closely I think you are probably right.

Looking at the back plate, it appears the clock has been fairly roughly treated by someone in the past.

Kurt shows the correct pendulum. The suspension guards were added during or after 1926. What's the number?

Thank you all for taking the trouble to reply
I missed the serial number before, it is 24164.
I still have the same problem, if I buy the 0032" spring and a bottom block, I do not know how long it should be - is it trial and error?
Thanks for you interest

One can get there by trial and error I suppose. Certainly the repair guide will give the details...there's another book...Passmore??...that can help. From the repair guide, the distance between the holes in the top and bottom block is 126mm. Be sure and trim things long because you can't add suspension spring once you've cut it off!!

Steve, here's your clock. The second photo should give you the correct measurements for the suspension spring. The pendulum shown here looks like a typical Kundo pendulum with the spiral center axis, but Kurt may be right as regards to an earlier time. Hope this helps!

Frank -

That is good info on the suspension spring. However, the pendulum with the twist rod came into being when the guide cup was introduced in 1933. That twist rod has an extension which fit nicely into the guide cup to keep it from wandering.

Kurt...

Nice catch! As usual your powers of observation (and experience) far outweigh mine. That should of occurred to my "old timers" brain immediately considering the several Kundo's in my collection. Thanks for pointing that out!

Cheers,
~Frank

From the number your clock is from 1928-1929.
