I didn’t want to take it apart too much looking for serial numbers but have taken detailed photos. The clock has always been in working condition until a recent move when two pieces became detached and it’s not been set up to work again as my father did this and he isn’t here to do it :)
The third to last photo shows the two pieces that came detached in a move, and the last two show where they go so you see they are complete.
Approx 3ft long by 17 inches wide at the widest part.
