Very good condition concertina in GC. This features modern plastic valves. 30 button Anglo style instrument with 20 G & C buttons and 10 “accidentals”. This uses Italian accordion reedplates and has plastic one-way valves. It has just been tuned to A=440Hz. Practically no wear on the exterior. Included is a gig bag. Better than new since I’ve tuned it (most arrive after import from China with poor tuning) and set the reeds.
