You can tell if it is a car clock since GM clocks at the time had one connection on the back for the (+) wire and it was grounded through the frame. There were also clocks that were called 'autoclocks' and they were self-winding units that wound up as the car bounced down the road. Autoclocks sort of came and went in the 30's though since they had to be reset every day as they would wind down. The were a popular Packard option.
