Вот румыны пишут, что трофейные сорокапятки появились у них зимой 41/42г
"n the winter of 1941/1942 there some changes in the organization of the cavalry brigades. The general structure remained. The heavy weapons squadron of the motorized cavalry regiment had now 4x60 mm mortars and the 37 mm AT guns were replaced with captured 45 mm M32 AT guns (this gun became the standard AT gun for the cavalry until the end of the war)."
