I also acquired a M99 in .300 Savage recently for $500. It is in very good shape, wood and bluing, and has a Lyman peep sight mounted to the rear side of the receiver. Its S/N is 575540. As far as I have been able to determine, the "B" code in the circle on the lever boss indicates 1950 mfgr. However, this B is preceeded by the number 23 which is also in the circle. Does anyone know what this 23 code means?
Second question: Have read references to M99 models such as E, EC, F, G, etc., but am wondering if these letters are appended to the M99 designation that is stamped on the receiver??
Thanks in advance for any assistance.
