Huvius' post of a M1911 M-S in .375 Rimless Nitro Express made me remember: Many years ago, in the 1980s, I visited a "name" gunshop in London. The salesman there showed me a Mannlicher - Schoenauer M1911 as a ".375 Holland & Holland Magnum". As it turned out, that man was not aware of the fact that there ever were other .375 cartridges besides the H&H Magnum.
