John,

I think there are a couple of pictures in Wolfe Publishings Wildcat cartridges...all articles from Rifle and Handloader magazine. From memory the rifle was in 303 and the author had it rebored to 303/375 as the original barrel was no good but he wanted to preserve the sights and markings etc.

I will see I can locate the book out in the garage and scan the article for you.

Mike
