A 1942 Swedish rifle was made as a M38 with a bent bolt at Husqvarna. The M96 rifles that were shortened are termed M96/38 and retain the straight bolt handle.
Those rifles saw a lot of service and were also shot in military matches for a long time. The fact that the bolt is not matching could lead to headspace problems and I would have the seller guarantee headspacing and carefully inspect the bore.
The Swedish rifles can perform great on the range and are a pleasure to shoot.
