Husqvarna was building the 9,3x57 and the 9,3x62 on both the 96 and 98 actions during the 1941/42 time period. The Models M46A, M46AN, M146 and M246 were all produced in that time frame. Production overlapped.
Some were simply marked Kal 9,3 the length of the case not being marked.
Not knowing EXACTLY which model you have or are looking at, I'd at least want a chamber cast.
