Ran into one of these the other day, never even heard of them before. Please tell me all the details. This one has the serial number lower side of topstrap and 042 in white where you normally see the model number. Hammer, trigger, cyl release look forged and it wearing a pair of slim profile pachmayrs. No box or docs. I've done a search here and found a few threads with the last a little over a year ago. I'm wondering about the Pachs, did it come from the factory with these or were they added later on? These do not cover the backstrap. It has a hi-polish finish that looks black, is it considered a black or blue finish? Anything else that pertains to this model would be helpful. Thanks
