Reply With QuoteAs toolmaker, gun/bike/everything mechanical serial fiddler/repairer/...this looks like a well executed "special"... I wont say "home made", as more than one person I know has a garage set up of mills, lathes, tool grinders etc.,...that would put some gun producers product finishes to shame with the things they make at home (they are both model engineers) and that description would not do it justice.....either that or perhaps a prototype or pre-production/ evaluation mule of some sort....probably way off the mark here, but its just my personal opinion...
P.S. if it as stainless, I hope that is silver used on the brazed fittings.
