Best place to find out is the Jouster Culver Shooting Page at ; http://www.milsurps.com. Go to the 1911 Forum. Alot of Collectors there. I saw a Left-handed Randall once but it was way outta my pay-grade. Great bunch of guys on the CSP, they'll be glad to help and, I wouldn't be too surprised if you find a buyer there.
Oh, when you get there? They're magazines, not clips. They'll correct you real fast on that.
