English Wheatstone Concertina 48 Key w/Case

This is part of an estate sale. My guess is it is from the 1960's give the serial number 37000 but I don't really know. All the notes seem to play... the bellows seem in fine condition and case is good. No crushed sides or big dents

Hope to close auction early to highest bidder 6pm PST today 6-24 :-)
