No excuse for whomever the dealer is, but to be honest, there is little information out there on Swiss lugers. So, they continue to use the ''old terms''.
Many dealers, young and old use older books or what they were told. There is likely more information on Swiss here on the boards that is accurate than most books.
My personal irritation is the word ''rework'' when talking about police or Simson, but usually police. Its assumed that they were all reblued and thats okay. NO, but thats one of my irritation points
