Seems like a lot of knowledge and experience here on this forum.
Im fairly new but a long, long time S&W fan. Over my many years owning the range I have acquired 19 different models of smith handguns, all revolvers.
I own a like new mod 18 and a low sn # K22 (25723) and a couple of mod 34s with 2" barrels, nickel plated.
My question after looking at the K22 and 18 is what difference is there in those and my mod 34s and in looking, I don't see much difference in them and my "K" Frames.
I also just lucked onto a pair of Mod 27s, 3" and 6" new in the box, never fired for $450 ea.

If I can figure out how to post pics I will do so with ea of these revolvers.
BTW, I had never seen a mod 27 and after getting these two I have to say I have never seen bluing as deep and good as these two guns. I had no idea that Smith ever accomplished bluing of this quality.
