It does appear that the spring tension / strain screw is a phillips head, but the Phillips company began marketing the Phillips patent screw in 1933.
So, it's possibly correct for the 1940s. And the sheet metal work is very reminiscent of German machine gun and machine pistol construction of the late war period.
