Ex neighbor has a pre 64 fwt. CARBINE in 300 Sav.
Pretty sure they ain't growing on trees. I have a chitload of pre 64s and everthing about the gun looked kosher to me when I held it (droolin')
Now that's a very rare one. The .300 Savage is the rarest M70 chambering, catalogued only in 1947 with a total of only 362 produced. Additionally, the .300 Savage was never catalogued/offered in the carbine configuration....
