This would make the "lend lease" commander rather silly, who they lend leasing it from? Themselves? So its definitely a mainline weapon they built, not a weapon they bought from the Swedish, but rather a weapon designed in Sweden, than its design was mass produced and modified by Brits and US for their own uses. Also it seems like the bofors used (according to wiki) by the brits was a licence to build, and than the US started building them and yada yada. This seems like a very strange thing to do to the brits, even though they + all the allies used bofors extensively, and without their usage of the weapon, it wouldn't be known to anyone. Which is silly, its like saying "you cant show zippers unless its on Swedish people because they invented it!" So if you say "because designed in Sweden" than it would never be used.

I think the problem here would be that sweden wasn't actually in the war.
