Retirement project. Never even held one before let alone try to repair one. A 20 key Klingenthal Concertina made in the Republic of Germany. Bought it from a guy who had never used it so it was stored in a garage. Consequently the left hand side internals have all come adrift. The wooden construction not a problem it is the reeds. See picture. It probably wouldnt have been a problen if they were just all vertical but five are horizontal and I havent a scooby do what they are. In a word HELP! I pressume the wood to wood is wood glue and wood to reed is wax but what wax, is it bees wax?
