Far too overpriced, seeing that that rifle was one of the 1st. .458 versions that did not have the second, barrel mounted recoil lug to help prevent the stock splitting. Elmer was probably given that rifle by Winchester to promote the .458 WM as dangerous game stopping rifle. The Winchester Super Grade "African" was introduced in 1956 and according to Winchester's serial # records for the Model 70, Elmer's one (#380857) was made in late 1955. I recon Elmer didn't shoot that rifle a whole lot.

Jack Lott had an early Model 70 African that cracked the stock as he was just sighting it in. Winchester corrected the problem a few years later by adding the second, barrel mounted lug.
That said, someone will no doubt scoop the beasty just to have a Keith owned rifle.
