I would guess it used a rotary cutter to mill the threads...I'm looking at two Luger barrels and the cutter marks (and end of cut) are distinctive...
Also a 60º (or whatever angle the Germans used - 55º?) thread cutter, this one is for a vertical mill...I would further guess that the Gewindeschneidmaschine used a horizontal cutter, probably on an arbor, with a much larger diameter & number of teeth...
