I have seen one of these exactly one in my life, at Dusty Strings (Seattle) for $325 back in 1997.
I had been in the market for an official Dobro mandolin, don't know why I didn't pick up this Del Vecchio, which seemed like a nice little piece.
I believe I have also once seen a Del Vecchio resonator guitar.
Does anyone have any info on these mandos? Google (and years before, AltaVista) have never given me any solid info.
Did I just imagine that I saw a Brazillian resonator mando?
