This is awesome!!! Ok, maybe not 'awesome', but a really neat thing.
This:
is a FULLY FUNCTIONAL (circa 1950s) technician's model of a Hammond Organ mechanism!
Runs off of 2 D batteries, and actually outputs audio!
Has 2 tonewheels and drawbars, and one working key.
Really neat conversation piece, anyway! I've seen pictures of them before, but never seen one in person. I really lucked out on this one.
The guy was very nice, and even gave me this (mid-40's) technician's manual, complete with penciled-in notes and a 1944 complete price list. Cool.
