Hello all

Can someone steer me to a website or look in your reference books. I have 2 Winchester Mod 70's I would like to know the lineage of.

Mod 70 Safari Express G344265 chambered in .458 Win Mag 23 inch barrel

Mod 70 Has "Super Grade" on the floor plate G1435925 chambered in .458 Win Mag 21 inch barrel

Thanks

CF
