DedHed,
His "well educated opinion" is wrong, not all police lugers received the sear and mag safety, as noted in my post above. The "removed markings" show it was issued to the Schupo - can't make out where. Schupo = Schutz Polizei = "protection police". Obviously he did not know that the lugers of the barracked police did not receive these additions.
Your luger is not make up of left over/unmarked pieces- the lack of the DWM roll mark was explained above as part of the not delivered "Riff contract".
Lugers destined for the Police in this time frame were accepted by the military, hence the markings on the right side. There has been much discussion as to whether or not these lugers were first made in 7,65mm and then the barrels changed to 9mm- you can find the thread with this discussion by searching or maybe someone will post a link.
Yes, it looks like you should replace the toggle pin before shooting- as it could cause a problem.
Lugerdoc on this forum will have a replacement.
Herr Kaiser,
The cd mentioned is available from Simpson's or was- you have to call and ask for it as it is not "advertised" and was than $40 when I bought one.
Maybe you can put it on your Christmas list?
