Hello, I have two Winchester model 70's that are post 64 rifles, that were made for a short time starting about 1969 and going until 1981 I think. They both have a 5 digit serial # that starts with "G". The model 70, super grade 270 is serial # G18180, and the feather wt model 70, 7mm-08 is serial #G40993. Both are the controlled round feed with the long claw extractor. I have tried to find when these two rifles were made so I can add that to my records, but have run into conflicting info all over the net, so of it pretty old. Can someone with this knowledge help me here. Thanks much in advance for the help. Keener
