I recently purchased a very small, Warnant action rifle. It is chambered for a straight cased rimfire cartridge of a caliber consistent with the 6.3 marked on the underside of the action. I presumed it to be Belgian or German, but do not recognize the proof marks. No markings on the barrel flats or rib. Underside of barrel stamped P. Bisch??? in oval. Can anyone help identify the maker or cartridge?
Thanks,
Bob
