Re: 47 car clock
The clock in my '46 Super Deluxe quit a year after being repaired by an expert. I took it on to try repairing it myself, and it is still operating five years later. I removed the clock, pried the crimps on the chrome trim to separate the case and access the works. If your clock is the same as mine, there are a set of contacts that when made, cause a small solenoid to pull the winding arm back on a ratcheting gear to put tension on the drive spring. (Think of taking repeated turns on a bolt with a socket and ratchet.) The spring will drive the mechanism until contact is made and the cycle repeats. I got a small amount of clock oil from a local clock shop, used the tip of a toothpick to oil the rotating points and cleaned the contacts. Before I reassembled the clock, I ran it for a week on the bench using a 6V battery, and adjusted it with the adjusting screw to keep accurate time. (As good as it can be with an old clock)
Unfortunately, I took pictures when I repaired my speedo/odometer, but not when I worked on the clock, but I hope these help a bit.
PM me if you want, and I can give you more info.
