I am in need of the help of the collective experience of this great forum. I recently purchased a .458 WM from an older gentleman who has sold off his 60+ year collection. This rifle is built on a Mauser 98 action and is beautiful, it was made by Harold E. MacFarland, I do not know when or where. It was made for an individual (who I will not name unless I can get his permission), I have been unable to find any date on the rifle. It has an offset Paul Jaeger scope mount (the first one I have seen). The wood and engraving appear to be first rate. I have googled and have only been able to find out that Harold E. MacFarland wrote a couple of classic gun smithing books, one he co-authored with Bob Brownell. I have ordered both of these books from Amazon and should have them next week. I am seeking any and all information about this rifle, the maker and the scope mount. I appreciate any light that can be shed on these subjects. I would love to know when it was made and if there are any others like it. Thank you.
