I'm looking at one (M67-1) at my LGS. It's got Pach's and the rear sight appears to have been replaced (...it's black and just a bit rougher than the rest of the gun). It's stamped "DPR" on the left side, under the cylinder. Priced at $450; seems a bit high in these depressed times, but as someone posted earlier: these things just aren't seen that often. Fair deal? Anybody know what "DPR" would have been from? I'm looking for some help here; talk me down from this ledge. -S2
