Nice looking piece, it must have sat in a dresser drawer for a loooong time to be in that shape. K-22s seem to have very specific regional hot spots as I got a very nice one out of Souix City, (or was it Souix Falls) South Dakota for almost 2/3 of what one goes for in Minneapolis. That was a couple of years ago but the shop had a couple on hand and said they regularly can through. I can't remember the name of the shop, the owner'sname is Steve Naatjes though. I met him and his son while shooting sporting clays. the service was top notch and the gun was in better shape than described. The name of the shop is eluding me, if I ever remember it I'll post.
Top breaks aren't hard to find and some are quite reasonable. Take the Webley for instance. They can be found at nearly any gun show and the sellers sometimes seem ready to give them away. They are ugly and heavy but they are about the cheapest "quality" top break around. ammo can be scarce but you can always find one in .38 S&W or even .45 ACP. Top breaks are great conversation pieces but I wish the design wasn't so poor. Long term use can really loosen some of them them up.
