I’m having a hard time figuring out how to date it.. the serial number says 1650 3, with the 3 spaced off a bit.. bell says Elkhart Corp. and the bead wire is magnetic, which someone on another thread said that it was likely a 70s era Elkhart corp. model.
Anyway, I’ve always been curious about her origins. We’ve been through a lot in our 20-odd years together, and with my uncle 30-some years before that, and (imo) she still plays beautifully!
