I recently picked up this Benjamin Franklin 347 from bigragu for 165 bucks. I feel like it was a good deal. Check out how good the finish still is on metal. I ran the serial number on a website and believe it's from the mid 70s. The stock has a bunch of scratches as expected but the seals have been replaced recently and the pump locks up solid as it would have been brand new. I do have 2 questions for owners of these guns. First is what lube do you recommend to keep the seals in good condition and how often does it get a drop. Second is can this receiver accept the Wilson peep sight? I noticed two screws on the side that look like it would work but not really sure about it. Anyway I always wanted one of these guns and now I have it. Looking forward to getting it over a chrono and doing some testing for groups. It is a workout tho!
