Questions on a 1938 S/42

[thorin6]

Signed in yesterday to find it's been 4 years since I've been here. Still the best place in the world to research the P08 pistol. After perusing quite a bit of information, I've got some questions that I've not been able to get answers.
I picked up a 1938 S/42 P08 rig this weekend; pistol, holster (with loading tool), and extra magazine. Original finish (I've checked for tool marks, they seem to be all there) a bit worn. All matching as far as I can see (I haven't taken it apart yet, that will come later) and the grips are correct (marked 74 on the left grip). Both magazines are black plastic bases marked fxo over wing over 37 and P08 near the base. Tool is marked wing over 655 (thank goodness for magnifying glasses). Holster marked P08 and dtu 41 with WaA163 under the wing.
The markings on the pistol have me scratching my head; the serial number is 5174 with a v suffix; I didn't know they went that high. There are no proofs on the right side of the frame. There is a proof 63 under the wing on the barrel, and proof, crown over crown over U, which would indicate a commercial pistol (I think), and what looks like the same commercial proof on the bolt, but it appears to have been scratched over. The black plastic fxo bases come much later than 1938, but look like they have been with the rig for some time (the magazine in the holster has a matching chip in the base to a deformation in the leather).
So it looks like I have commercial frame that was diverted to a military pistol, but I have nothing to tell me that is correct. Anything that can enlighten me would be appreciated.
Pictures follow, if any more are needed let me know.
Thanks.
