Yes Don, After I posted these results I read further about the barrel proofs in your gunboards thread. I do believe it has the PTV/E proof on the right side of the barrel, however, it was very faint and I couldn't get a good photo of it. Also one of the proofs on the left side of the barrel does possibly look like a E/33 and another looks like an oval or football with an "S" in it. I may have a chance to see the pistol later today and I will look closer. If not, I will see it again on Tuesday.
Yes most likely the mismatch occured sometime after WWII. Also why the barrel/reciever was so heavily buffed and then reblued remains a mystery. My Trier Police story is just for fun!
I will report back after I have a chance to examine the barrel proofs more closely. I still think there is a good possibility that the barrel/reciever was a 1929 rework. Just like the frame and toggle is a 1929 rework. How the two halfs got seperated from their original pistols after WWII is a mystery along with how these two halfs got together to make this one gun.
Thanks again!
