So, I have a Whitworth .375 with express sights manufactured 5/88. I’ve recently acquired a Whitworth .458WM manufactured 5/85. The barrels are the same contour and length (24”). They have the same scrolling of caliber on the barrel. The proof marks look similar, except the WM has a “N” at the end. BUT, the WM has no sights AND no screw holes for sights? In my limited research of the larger bored (.375, .458) Whitworths, I’ve never come across one that has no holes in the barrel for sights? I guess the WM has a factory installed barrel, but now I’m not sure. Any input from the Whitworth experts here would be greatly appreciated. Thanks!
