The hinge pin was supplied .360,.365,.370;.375.Info supplied 15 years ago by a former Winchester employee who was working at Frank Lefever at the time. Name, Steve something. Different pins were used to fit multiple barrels. The locking bolt is the likely cause and I have replaced many of them. Not so bad with original ones,but the Galazan ones usually need the diameter reduced.Several years ago,I spoke with a person at the Winchester repair shop (new one)and mentioned the pin diameters and his comment --So that is why we have 4 boxes of them? Checked diameters and see above--4 boxes.
