I think the .450 Marlin started out 30 or more years ago as the ".458 American" which was a sawn off .458 Win. case made to fit into a highly modified Winchester Model 94, made by a custom gunsmith for his own personal use.

From the bit I read about the person who took all of the African nasties with a .45-70 Marlin, I got the impression that it was a stunt. The account contained too many references to wild parties for me to think otherwise.
