Thanks for the information and the pictures - the top you made looks pretty authentic. The interesting thing is that the Executive model that I have, has the top portion of the battery terminal located in the top of the column..there isn't a separate "top" per se. The piece that I'm interested in getting information about is the "back" of the column - it is open the full length, down to the base of the clock. So I'm not sure that this battery cavity would have been covered or not, and if so I would guess that it would be about 1-1/2" wide, and about 6" in length and slip over the back of the column. And to be honest, I'm not that familiar with the clock and it may not have even had this "back" piece in the original design - so I may be all wet on this request. However, I really do appreciate the information. Thanks, Mike
