I would appreciate some feedback about this clock which is new to me as of Feb 2020. The movement is marked “Waltham Clock Co. Sweep Second Model”. See picture. I think that this clock started life as an E. Howard #1 Banjo Clock. The size is the same as a #1 and the shape of the case is the same as a #1. I think that at some time in its life someone skillfully fitted the Waltham movement with a sweep second hand. Another curious thing is the “secondary winder” at the 9 o’clock location. What’s it for? While examining the clock case I found a “trap door” in the bottom of the pendulum box. Check out the picture. Could it be that for some unknown reason the “skillful horologist” that fitted the Waltham movement wanted to be able to adjust the weight drop. The weight drop could be adjusted using the “secondary winder” after opening the “trap door” on the bottom of the case. This clock came from the Andy & Bea Copeland Collection in Texas. When I set up the movement to test run it the movement was seized – not because it was dirty – but because there is insufficient end play for the arbors. I loosened the pillar screws a half turn and, bingo, all parts of the movement turned freely. I look forward to your feedback. Thank you.
