I came across a Model 42 today and could use a little sage advice. I am new and a novice, and frankly this was the first one I have seen since I was a kid not paying any attention (so I have no frame of reference). The SN places it in 1973 (as per the definitive thread). When I first picked it up I thought it had been refinished, the alloy frame is a very deep, dark, glossy black and has very little wear. The steel cylinder is a more typical blue, thinner and less of a polished look. Over all there is little wear, almost none, which led me to wonder about the finish on the alloy. The logo can be "felt" and does not appear to be worn by refinishing, the grips have lost some varnish in a few small spots. They are the low horn, smooth type. It has no box and the price is $499. Is what I have described accurate for an issued, non re-finished M42? Your thoughts on the price? Thanks in advance.
