Bud Those Green River Leman rifles are true POS, but being as how I'm such a decent sort, I'd be willing to buy it for a modest $, and save you the hummiliation of being seen shooting it :wink:
All kidding aside those are beautiful rifles, as far as value you could keep an eye on sites like auction arms, as they do show up on occaison,
I can tell you it's not some really valuable collectors item, but they are a
fine rifle, one I'd be quite happy to own, I had a couple of crazy hippie friends back in the 70's, they owned a really cool BP shop in St. Charles Ill. (The Powder Keg)it was in a Ghetto type neighborhood, but they never got broken into because the Yo's would literaly cross the street to avoid us as we all had long hair and beards, rode Harley's and would be out front throwing tomahawks and such they doubless thought we were insane.
At any rate those guys looked down their noses at most production BP rifles as they built really beautiful trade guns,rifles and fowlers, they thought just about any factory rifle was garbage, but they did sell Green River rifles, I had my eye on one of the Leman's but never had the money and I regret not buying it to this day, at any rate t'were I you I'd work up some good loads (with real BP) and start shooting and enjoying that rifle, they're very fine shooters.
