Thanks for the quick answer.

I had not thought of the possibility that Savage might have made their own stocks.

It makes quite a lot of sense — but if they were making several different firearms, even in peacetime, they still may have found it necessary to contract out for at least some of the rifles.

I may try contacting Savage Arms to see if they can tell me anything.

I had a short email conversation with Brian Dickicon, who said he thought they had lost their records in a flood, so I may have hit a dead end.
