I recently acquired a Winchester model 70 in 375 H&H. It is very nice, but has apparently had the barrel band for the front sling swivel removed - or perhaps there never was one. Anyway, I was wondering if there is a simple solution, other than having one installed by a smith. They also removed the iron sights, which I would like to replace. This apears to be a circa 1971 vintage gun with a really nice stock.
