I bought this clock yesterday for $10 thinking that I was going to have to completely overhaul the movement to get it working, and that this clock would be good to learn on before tackling the nicer ST 124 I have. When I got it home, I was pleasantly surprised to find that it runs and chimes and strikes. Then I noticed that there is a big chunk of wood missing out of the bottom of the case. So it looks to me like this project is going to be more carpentry than clock repair. I see strong evidence that this clock has been dropped - the missing glass from the bezel, the chunk of wood missing from the bottom of the case, and the fact that the hinges holding on the back door are bent so that the door doesn't close properly. I have three questions I am hoping somebody can help me with: 1. I'm thinking that the best way to repair the bottom of the case is to pry out the bottom panel that has a chunk missing and replace it, carefully measuring where to drill two holes for mounting the chime rods. Is that what you would do? 2. Unlike my other ST 124, I don't see a chime shutoff lever. Does this model have one? The back plate of the hammer mechanism is stamped 124F and a date code 4610 which I think means October 1946. 3. Does anyone know what the opening in the dial just to the right of the 5 is? There are three openings for winding the springs and another one up at the 12 for regulating the clock, but what is that other opening for? Thanks in advance for any help.
