the Model 46 was in production from 1927 -1937. than came the Model 146 with a belgian made Mauser 98 action but because of WW 2 Husqvarna was forced to go back to swedish M 94 actions in 1942.
this was the Model 46 A and the only real difference is the pistol grip with a cap. the Model 46 have a round pistol grib.
