I have a pre 64 22 hornet super grade serial # 290043 that is noted on the barrel K 222. I am under the impression that it was re drilled to be a 222. I can find no real information on this specific gun. It is in excellent condition with no dents dings, pitting etc and the bluing is excellent as well. Would appreciate any information that you may be able to provide as to the history and value of this gun. Thank you for your assistance.
