Here's a lot of the mechanism for a nine inch Mermod interchangeable music box sitting in a non-original case.
The spring is not taking tension and there is no start-stop.
The comb is in very respectable condition, no broken teeth. This mechanism could be very useful for the comb, cylinder, governor and crank, and possibly some of the associated gearing.
You can hear the box being hand-turned on the mp3 file.
We buy, sell, and repair antique phonographs and music boxes.
Pick-up and delivery possible in many parts of the midwest,south, and northeast.
