Mine shows more wear than yours, however, I would NOT reblue it. Get yourself another deeply blued specimen, and use the heck out of this one. Unless it's a poor shooter, in which case, send it to me and I'll love it.
+1 --- the gun, as is, shows good honest use and character. As "redlevel" said, get rid of the smooth grips and find a good used set of diamond magnas and a T-Grip!!
I gonna go against the flow on this one, guys. It's your gun & it depends a lot on what you're gonna do with it, as well as what you've already done to it. It's doubtful that it'll ever be more of a collector than it currently is. Yes, it has some character, but unless that wear and pitting has some emotional significance for you, it's very likely gonna start bugging you at some point. If I had it, I'd seriously consider hard chroming it: http://mahovskysmetalife.com/
My rationale would be that I've already got a couple K22 safe queens, as well as some others with "character", and I've never seen a hard chromed k22. I think that it could be kinda neat, and that it would preserve the usefulness of this particular gun for another generation, at least. Let the flames begin. -S2
OK-I'm with Wyatt-reblue, but get a master to do it. Here's a couple by Gene Williams. Simply beautiful. One's a pre-war non-reg magnun and the other is a plain ole 10-5. Both give me great pleasure in their restored state:
