I have come to own a beautiful Winchester 71 that a gunsmith artist converted to .450 Alaskan long ago. The original owner passed away 40+ years ago and it has sat in storage since that time. There was no information as to who made the rifle and the friend I purchased the rifle from is the son of the original owner and he was a small child when his father passed so he has no info on the rifle. However there are clues on the rifle and in the work that was done that are distinctive and I thought perhaps someone who is knowledgeable with such conversions may be able to solve the mystery of who did this work. The barrel is marked on the left side of the barrel near the reciever".450 ALASKAN" the right side of the barrel is marked "B." and below that "6-65". The fore end tip is unique and beautifully made with a clever fixture anchoring the cap to the barrel that is distinctive in design and was well thought out and executed (see pictures). Additionally the barrel has 12 deep grooves and lands and the rifle has a full length magazine tube with a distinct fixture at the muzzle end and even the barrel is scalloped out to provide a snug hollow for the mag tube to set securely into at the muzzle. An intermediate eye relief 2x Leupold scope was mounted on the barrel sometime after the rifle was built (unfortunately) but it is clean. As the design and fixtures are distinctive as are the markings on the barrel I hope that someone familiar with these conversions from "back in the day" may recognize who the craftsman was that built this fine rifle. I have attached a couple photos. Thank you for any information you may be able to provide as to solving the mystery of the origin of this beautiful rifle.
