Nice K-22.
I've always liked them and have collected examples from post war, up through the '60's. Some -3's too.
I have a few gaps and a few doubles but that's fine with me.
I remember joining the SWCA and when they ask new members what they liked best I said post war K-22's, it got a big laugh.
They were common and good ones went for $400 back then, so they thought my sights were set pretty low!
