>it wouldn't take much to make the gear and restore the workings of the patent model,
it would be nice to see it functioning again.
You are correct, I'm sure I could tear down a couple of old clocks and find the little drive pinion gear I need, solder its shaft to a small crank, put in a couple other bits of metal, and there you go.
I've got it on my list as project number 1,754. I'm working on no. 93 right now. I hope I can still hold a screwdriver when I'm 127.
