Update - This is in Pete DeCoux’s current auction
I have one original condition loaded 7.92x94 with primer, powder, and projo intact. It has the red primer and case neck seal and might be the tropic variant?? The bullet reacts to a magnet as if it were steel jacket, and it should have the steel core, and tear-gas pellet as well of course. Only condition issue is a couple age spots which could probably be brushed off if desired - shown in pic below.
