A Canadian friend of a friend has what appears to be a Savage 340 rifle in .222 Remington with no brand name on it. The caliber is stamped on the barrel, as is a proofmark (SP in an oval.) Serial number is 125XXX. I guess it could have been sold as a Savage, Stevens, Springfield, or even a store brand. Any Savage experts out there who can come up with brand name and/or age? Thanks and sorry about the lack of clues.
