Hi folks, sorry if this is a redundant question, but i can't seem to find my specific model 99. i found the serial number and the maker's mark, but either my savage is mis-marked or it doesn't really exist. my rifle states that it is a 12M model 99. the serial seems to date back to 1961 (1014xxx), but i just cant find the "M" anywhere online. Any ideas?

thanks in advance
