As far as I know, Husqvarnas first freearm model was a zigzagger suspiciously close to the early Bernina 125. Both introduced shortly after WWII, the only obvious difference appart from the logo, is the green finish of the Husqvarna versus Bernina's cream. There was a green Bernina 125 too, but less common. I have never seen a freearm straight stitcher from neither Husqvarna nor Bernina close to these early freearms.
I think the first Husqvarna freearm model were made in Sweden, at the time both Sweden and Switzerland had an advantage when it came to production machinery, since they were less affected by the war effort. I'm not entirely sure on this point. The models are so simililar there has to be some kind of collaboration or licensing with Bernina. These are relatively small machines and somewhat similar to the Elna Grasshopper, but because of the build and zigzag feature they can't as easily be confused with the straight stitchers only. If you look at other early German makers of this era you can find a few freearm straight stitch only machines pretty close to the US made models.
A bit into the 50s came Husqvarna (Viking/Nordic) model 19, 20 and 21, stronger machines with a few more stitch patterns as well as a new bobbin case, hook and race. They have a different gloss to the paint. There were a straight stitch freearm model in line with the new design of these models, but it's not common at all.
