You want them for show or go?
I ask b/c I have an old V series 3/8 swivel that has seen better days....loose, surface rust that i was thinking about trading in for a new one. Hate to turn it in if someone wants one that is still useable, but has seen much better days.
I'd be more than happy to trade up for a new one if you want...better than it winding up in a pile of scrap heading to China!
