With a 12V DC power supply, I’m thinking that would make a most excellent desk clock once set into a custom wood base, stained a nice, rich grain-enhancing brown, with a deep luster poly coat and a tail number embossed below the clock…
Interesting how the main spring is wound with a solenoid-driven movement, not a DC motor. This is the same company that produced the majority of clocks from 1937-1984 for your Buicks, Chevys, Cessna and military. (In high demand for vintage vehicles.) Would your digital and LED clocks still work after 60 years?
