This clock didn't work so I removed it in preparation for installing a JPI FS-450 in that hole.

It's probably the original clock from my F model.

Took the back off just to see what they look like inside and found it's nice and shiny with no corrosion. On a whim, I gave it a squirt of WD-40 and it started working just fine.

I'm guessing the oil had dried out as it sat for 20 years while being disconnected from power and the WD-40 broke things loose.

The previous owner had self installed an iFly GPS and used the clock circuit for power. Then he installed a power switch to the GPS as that circuit is always hot.

Anyway if you want to try it, shoot me $20 to cover shipping and it's yours.

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…

I thought about getting it, but the 12V DC power requirement gave me pause. There's no compact 12V battery source to use with the clock.

Plug in power supplies are on Amazon for between $10 and $15.

Thanks, George. I've decided to give this a pass because the clock by design isn't very accurate. But This YouTube Video [youtube.com] explains how it is a mechanical clock but is "wound" electrically. Very interesting.

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?

I’ll take that clock. I’m gonna make it into a fancy desk clock. Take my money.

Lachlan, Send me a private message with your full name and address and I will give you the following aircraft clock which also is lighted.
Club members will look forward to the finished project. George Jameson has a good 12V solution.
