Lachenal Edeophone 61 key Maccann duet concertina s/n 3741   This concertina requires some restoration work but it will make a very fine and valuable instrument when this is done.   The issues are as follows:   There are 3 keys that require work, one on the right hand side and two on the left.   The 7 fold bellows has two pin hole leaks but otherwise look to be in good condition.   The straps are new but one has the threaded fixing screw missing.
