I finally found one of these in an estate sale (Winchester model 70 Pre-64). There has been some work done on it ie bolt face and rechambering, I have ordered a new barrel but it has the orginal box, spacer. spring, and follower. I know that Griffin & Howe did some conversions and want to know if anyone has information concerning this such as did they use 722 followers and did they pin or remove the shell pusher? Thanks John
