... I can't remember exactly when but definitely by the early 80s the 375 and 458 turned into the same gun and were called the Express and had the sling swivel on the barrel. The price of the Express 375 and 458 were still a lot more than the smaller calibres.
So all those yrs from 1937 Win didn't think they could make it in the market with an African Exp. priced .375 -
How much did a pre 64 375 cost as compared to 270/30-06 and 300 Win/338 Win.
Stuart Otteson in his book on bolt actions said when the Post 63 came out Winchester kept the 375 for marketing reasons and lengthened the receiver to properly accomodate the 375.
