Fine condition German made Concertone (Hohner factory) button accordion in ADG. It is in very good condition overall. The stained wood case is in excellent shape but some of the black wooden bellows frame shows paint chipping. The original bellows are very tight and show very minimal wear. It has 31 treble buttons and 16 bass buttons. 

As the photo shows, the metal grill is in great shape and almost looks new. The front and rear grill screens have been replaced. Unlike many of the Hohner boxes purchased used, this is ready to play without further adjustment required. I repair and tune button accordions and have specialized in older Hohner button boxes.
