I bought a couple of Swedes about 12 - 13 yrs ago(maybe longer?), when a batch came on the market. One is a Gustavs 1918 serial 460XXX. This is a model 96 with a straight bolt. I've sporterized it, but I recall not cutting much barrel off, so I'm guessing it was 24" originally.
The other is a M38 short rifle marked Husqvarna 1942. The M38 means they began making that variation in 1938, but they may have converted some older rifles. It has a bent bolt and is serial 644XXX. The two actions are pretty much identical.
There were also 94's. They have a much shallower thumb cut for the stripper clip and do not have the guide rib on the bolt. 94's would be pretty rare.
Bolt Action Rifles, by deHaas is a great reference
