The special recorder for the rare Columbia model AW. If you look carefully at the picture of the underside of this recorder you can see that it is marked AW. There's nothing standard Columbia about this recorder; it has a special fitting to allow it to drop down from an overhanging carriage, which would allow it to work only from an AW.
The original cutting stylus is present and seems to be in good condition (see image).
Possibly the only one in existence. If not, probably one of a handful remaining.
We buy, sell, and repair antique phonographs and music boxes.
Pick-up and delivery possible in many parts of the midwest,south, and northeast.
