Niklas,
IF they were forging "in-house" then retooling would have been required to make the dimensional changes. An expensive proposition. However, if everything is outsourced.... I doubt any German maker was supplying them in 1943. They may have been living off of in-stock inventory.

Pete,
I have a Husqvarna underlever hammer double made during WW2 time. It had never been completely finished and I had to do final fitting of locking lugs. Over years of use, it has become rather obvious that it was very likely assembled from "left over" parts. The barrels seem to have been made from two rather different quality steels, for example. One barrel is very rust resistant (like on all my old Husqvarnas), the other is not, exhibiting various areas of pitting corrision (which NONE of my others have at all!!).
While I have little direct information about outsourcing by Husqvarna, I would expect it. All Damascus barrels are reported to have been outsourced, for example. Ditto for early sidelocks and apparently receivers from Sauer. Don't forget Sweden's arms makers business relations with Remington, Nagant brothers, Mauser, Browning, the French, etc.
