Any Winchester Model 70 Pre-64 experts out there? Question: Were all the front sight hoods on the Pre-64's tapered on both ends? I think they were but my memory has been known to play tricks on me. I've been looking for an original pre-64 hood and have found a lot advertised as such but they have the taper on only one end. I think these are post-64 copies. The people selling these "replacements" tell me I'm wrong. What say you?
