I think I have what you want, but I don't know where to get
another. It's perfect for an encoder multiplier. It's a
60:1 gear box (2" diameter, .35" thick, 0.155 dia input
shaft, .047" dia output shaft with 2 mounting holes) that
was probably used in some kind of clock. I got it from my
dad's junk box after he passed away.

On the back is:

Bristol

Bristol Motors
Div of Vocaline Co. of America
Old Saybrook, Conn USA
MOD 4655 73A
748D-1 60:1

I can't find anything on the web about this company. I'd like
to have a couple of more or something similar, of these myself.
