Tradeexcanada had, maybe still has M98s in 9x57 Mauser for sale in the same lot as his M98, M46, M146 and M246 Swedish Mausers in 6.5x55, 8x57, 9.3x57, 9.3x62 and a few in 30/06. These all came over from Sweden, seems to me, so I thought they were all Swedish Mausers.
ALL of the 9x57's were M98's, though, none in M96's or M94's.
