Help identifying old cymbal

Found this on CL today. Seller does not know what it is. The lathing suggests it's an "A" but I'm not an expert. Is this possibly a 22" vintage K? I've heard they used to make some of these without stamps. I don't think it looks like a cheap brand simply because the patina and markings suggest significant age. I just don't think those cheap cymbals last that long. Any ideas? For $30 I can't go wrong I guess.
