About 30 years ago, Mr Kopriva gave me the remnant of a 12-string mandolin, consisting of the
shell back, neck (no fingerboard) and headstock. One set of 6 tuners and the bridge and saddle were included. There was no soundboard and the nut was missing, too. I started working on it at Bob Gorney’s ( a Chicago luthier ) shop. With his assistance, I put on the fingerboard and cut the fret slots, as well as glued on a soundboard. Then, I got distracted by life and forgot about it for 25 years…
