I got this very sweet build in a trade, solid Brass, some nice features, spot on frame geo.. Dude didn't have any history, built in 2009, really nice and heavy, still has original coils Buenos Aires 20 wraps. Has the initials BN and No 31 carved into the frame, obviously BN could have been the owner, and not the Builder...Any info would be appreciated...I know what it isn't (Sunskin), but I would like to know what it is...Peace,P
