Thanks Bob, but a couple of things are still unresolved: 4-line "Marcus Registradus" stamping and straight barreled extraction rod make me think it's a post-war, rather than a pre-war kit gun. Perhaps some post-war modifications? Likely that AR simply attached the writer's photo of his gun that he may have incorrectly identified as a K22. Regardless, I would have hoped that AR would have done better research. -S2
