I just bought this clock at an auction. I was not aware of ST making anything like a Boston Shelf Clock. This clock has a ST 89AL movement in it, but I think the case was made by a skilled cabinet maker and a ST movement was used in it. The one piece back board slides into a grove at the top and is held by screws on the bottom. The clock is 35H X 13.5W X 8D. Any information on this clock would be greatly appreciated.

The clock stands 35H X 13.5W X 8D in inches.
