As I recall, when Germany invaded Belgium, they captured the FN plants and stock, and began producing weapons for Nazi Germany, and you can find many surplus FN weapons, like the High Powers, with Nazi markings.

When my Father came through Liege not long after it was freed from the Germans, he said the plant was already taking orders from American soldiers for shotguns.
If the soldier paid, they would mail the gun to American once the guns were produced. Probably all kinds of laws now to prevent that.
