English concertina

English system concertina with hexagonal fretwork case and end plates of rosewood veneer. Three-fold dark-green leather bellows with patterned paper. Four straight rows of bone buttons on each side (48 keys): two C buttons stained in red; accidental buttons stained in black; and natural white buttons with note letters stamped on their tops. Dark-green leather covered brass finger rests. Dark-green leather thumb straps (one missing). This instrument belonged to Robert Beer from Somerset, who was a saddler and later a mechanic.
