What dates or serial numbers did Winchester change the 375 H&H rear sights from the Lyman 6W to the Winchester 70B?

Hi Begger-

Roger Rule’s book says the Win 70B was used on the 375 H&H Magnum C-1 contour barrels from 1953-63. In my survey to date I have about 210 M70 375 Magnum serial numbers recorded. Based on what I’ve seen, the changeover from 6W to 70B happened fairly abruptly around the 300-310 thousand serial number range (1954). So we’re pretty close…

Hope this helps,

Lou
