Frigid Fracas by Mack Reynolds

To Mauser's surprise, the Sovs actually turned up two genuine Bowie knives. He had expected the duel, actually, to have to be conducted with trench knives or some other alternative. But the Sovs, ever great on museums, had located one of the weapons of the American Old West in a Prague exhibit of the American frontier, the other in Budapest itself in an extensive collection of fighting knives, down through the ages, in a military museum.

Formally correct, Lieutenant colonel Bela Kossuth appeared at Joe Mauser's apartment three days before the duel, a case in his hands. Max, in his role as batman, conducted him to Joe, doing little to keep his scowl of dislike for the Hungarian from his face. Max was getting fed up with the airs of Sov officers; caste lines were over here, if anything, more strictly drawn than at home.
