1920 Club system button accordion.
Made in Klingenthal Germany.
Instrument comes with about 10 books of songs and sheet music for this instrument (club system)

Instrument is in generally good condition and the reeds are free of rust. Reeds are steel on zinc plates.
Wax needs to be replaced along with the leather valves.
Bellows are in good shape except that someone decided it would be a good idea to retape them with duct tape. This could be removed without harming the bellows by using a hair dryer.
black button indicates the "gleis tone" (same in both directions).

Comes with case.
