I have a Tradewinds catalog No. 22 which I think to be 1969. It lists the Husqvarna models 8000 and 9000 in it. Both 1900 actions. I have a model 9000 of my own chambered in 6.5x55mm. It is stamped a Husqvarna 9000 model and has the Tradewinds rollmark on the barrel. It is a 1970 manufactured rifle according to serial number. I am guessing Tradewinds only had the 1900 actioned rifles for a few years at most. That is just my guess. I am sure there are plenty of people better studied on the 1900 actioned rifles than I am. I am not certain exactly when the Carl Gustaf nomenclature began and the FFV Sports did importing? As for the Krico 5000 and Huskys, I am not sure when they kicked in?
