By 1940, there were only three large factories making military Lugers: Mauser (Oberndorf), Krieghoff (Suhl) and the Swiss W+F (who were making their new pattern pistols).
DWM had closed the line in 1930, Erfurt at the end of WW-I in 1918 (it's tooling and gauges taken to Simson in 1925 and then Krieghoff).
After 1937, all the Mauser made receivers had the "Hump" on the receiver ears at the back.
This one is dated 1940, and has no "hump"... What is the possibility it's a Krieghoff receiver? Is that a real Waffenamt proof stamped on the right of the receiver (the eagle looks like it has an unusual number of horizontal lines)?
So, given the "42" marked Mauser rear toggle, the DWM serial numbered frame and forward toggle, this is a mix of parts from different factories.
in the first of your second set of pictures showing the front of the frame with serial number, it looks like the frame is a couple of millimeters proud of the front of the receiver. If this is the case, it could have an early long frame and a later receiver. I don't know if I'd trust it's safety or reliability if this is the case since it might fire, but could impact the cycle timing.
