A friend asked me to take a look at this steel plate Waterbury. His only concern was that the springs make a noise occasionally. Probably sticky with dirt and releasing sporadically as it runs down, my guess. And that a spring had been broken and repaired sometime in it's past and he winds it twice a week as a result. In the clock both springs appear to be about the same length. Will know more when I tear it down. It is dirty and needs a good cleaning. I believe he said it hadn't been serviced in over 40 years! It was a wedding gift to his great grandparents. But the thing I first noticed was the bushings. Looks like they have all been replaced to me and look to be way oversized in the frame? And the surface on each bushing is slightly mounded and not smooth.? Maybe peened to compensate for wear? They all appear to be tight, (at least with all the dirt), might show a different picture when I clean it. The other thing I see is the small rounded flathead screws holding the frame . Have never seen that either. All said and done the clock runs and strikes well as it is. Most likely, I'll just clean and lube it and put it back together.
