Hello, I acquired this case and have been doing my best to understand what it is and how to find parts for it. Most recently I was shown that it is very similar to a Welch, Spring, and Co Calendar No 3 only made as a shelf clock. It is right at 44" tall and does have one pulley but with the wind position @ 2 o'clock I can't find anything that gets me closer to being able to rebuild this. Any help you can offer would be appreciated. If I can understand what it is I will then be able to start my hunt.
