    My experience is that the problem is most likely the strike rack tail is not adjusted properly, allowing the gathering pallet to miss pick-up of a rack tooth at the 7:00 position. Moving the hour hand will not solve the problem as you have discovered.

    Adjustment of the part will require removal of the hands and dial, then adjustment of the rack tail to ensure that a rack tooth is picked up on every half-rotation of the gathering pallet. Note the gathering pallet has two lifting pins so each pin should pick up a rack tooth with each half rotation. I am attaching a photo of a GB grandfather weight driven time & strike movement that should be similar to yours. The parts I have described are labeled for your information.

    Note that the rack tail is not in the correct position in the photo; it should be below the snail with the position pin underneath the snail. The rack tail is adjustable at the center where it is mounted on a post, there should be a locking screw that can be loosened and then the tail moved slightly to adjust the position of the rack teeth to allow the gathering pallet to pick up one tooth on each pin. The tail is a friction fit so it may take a little force to move.

    It will be appreciated if you could post photos of your clock including a full view of the front, close-ups of the dial and back plate of the movement, and also a photo of the gong that will be mounted in the back of the case. We can accurately date your clock from the movement serial number and possibly provide a model number for the case if it has been illustrated in one of the GB sale catalogs we have available.

    I agree completely with John's description of the likely problem. Just had one that needed just a minor adjustment to strike rack to stop mis strike on 1-4 o'clock. I would add that you verify the strike rack freely moves and lands the same each time. Also inspect the rack teeth for condition. Also that the problem is always in the same hours, before making adjustments to rack. Joe

    Also check that the little pins on the gathering pallet are not bent in such a way that they don't always catch every tooth the same.

    I've successfully repaired it. There were more than one problem.
    I'd like to thank you with the other friends who did share.

    Mario, thanks for the additional movement photos, those are quite helpful and I will provide a date and other information in my next post. Do you have a case for the clock? I had asked for photos of the case, also the gong so we can do a complete documentation.

    Mario, you can add multiple pictures to one post. It would help to keep things more manageable on the BB ;)

    Is this the same clock you already posted about, or a different one. We need more details.

    Mario, thanks for the additional photos. However, please note that you can post up to 10 photos in each post, which makes it much easier for us to see what you are presenting. If you need assistance for this there is an instruction thread at the top of each forum how to use our photo posting system.

    I was hoping the photo of the back of your movement would be clear enough to see the serial number, however I presume the actual number is what was written on a paper that you posted. Based on that serial number, your movement was made in the January-March quarter of 1904. I notice the pendulum length stamp (P 65.5) on the back of the movement shows it is 65.5 cm long, which indicates this movement was most likely made to be mounted in a large Vienna regulator case instead of a medium size grandfather case.

    It appears that the case for your clock was made by a craftsman or hobbyist (not by the GB factory) some time later than the movement was made. It is a traditional design and has a generally pleasing appearance, however there are not any designs like this one in any of the GB sale catalogs available. There are a number of indications of hand-made assembly and finish; for example the mounting of the movement support bracket is on a raised plank of modern grooved wood and not directly on the back board of the case. The dial also appears to be from a later period than the movement, likely by 20-30 years. However, the hands are correct and fit the dial.

    Re: Gustave Becker clock

    Mario, your clock has a beat adjuster at the bottom of the crutch which is adjusted almost as far as it will go to one side in your photo. I would adjust it back to the middle of the crutch and then set the beat by holding the pallets with one hand and gradually moving the crutch, allowing it to slip on the arbor, until the clock is in beat. When it is in beat, you will hear the tick at approximately the same distance from the center of the pendulum swing on the left side and the right side. Once you reach that point, it is easy to adjust the beat with that adjuster on the bottom of the crutch. It should keep running once you get it perfectly in beat.

    I have merged these threads, Mario. It's just too convoluted to have multiple posts about the same clock!
