Dear alaint Milfoam Forrest Bore Cleaner is this:
Not something authentical which we make from horse milk ;-)
If I didn't understand wrong, the Frame (Griffstück) was made before 1908 due to not exsisting stock lug, the chamber (fork, I would call, taking the German "Gabelgehaüse" in consideration) was the dated 1910, so it was made in 1910. That means the chamber was made at least 2 years after the frame. This also explains why there are no serial numbers at the side of the fork (or chamber). Most probably, they have erased them before installing it.
The rear toggle link (Hintergelenk) was made in 1900 or before. So it was made at least ten years before the chamber but might be the original rear toggle link of the pistol because the frame was made in some year before 1908. Are there common mark which would help us to distinguish the production dates of the rear toggle link from the frame?
In conclusion the frame and the chamber are mismatches, the rear toggle link and the chamber are also mismatches. The frame and the rear toggle link MIGHT manufactured in the same year.
If we summarize, this pistol is not a matching parts, Luger. Am I right?
What would you add on this information?
We would really appreciate any information about this particular Luger.
PS: Although it was assembled from different parts made in different times, it functions at the range like any other modern pistol, interestingly.
