Just picked this up. It has the full "New York" inscription on the slide, high screws on the grips (no reinforcing rings), an HS barrel, Stubby hammer and so on. All the bits seem to indicate the first variation except that the sn is 9266xx which is a bit over the limit they specify on CoolGuns. The finish seems to me to be uniformly worn and the barrel is consistant with that level of wear. Thing is that some of the marks are light, some are not. I have no idea how consistant these things were. The other thing that I found odd is that the bluing on the barrel gets noticeably lighter right behind the ejection port. Not sure the picture will show it well. The difference is on both sides. Was there some sort of heat treating going on that would cause the bluing to "take" differently? Seem to recall reading something about that. Anyway, I'd appreciate all thoughts. Thanks.
