There's Colt, R&S, LeMat, why no Walch?
Why should there be. They're pretty rare. Only 4,700 made all told and only 200 of those were 12 shot .36 caliber. The rest were 3,000 iron frame .31's and 1,500 brass frame 31's.
There's also no forum for Joslyn, Freeman, Manhattan and a host of other revolvers.
