Parts Mix and Match

I just purchased a 1914 Erfurt LP08, S/N 5574. It has a fine tune front sight and non-fine tune rear sight. The rear sight is apparently DWM (no proofs) and all three parts are numbered 96. I know it is a very, very slim chance but maybe someone out there has a #xx96 LP08 with my #74 rear sight - and I have their rear sight. Trading would be nice. Along the same lines, mine has a DWM #74 breechblock/toggle assembly. Maybe somebody has a #xx74 DWM LP08 with my #74 Erfurt breechblock/toggle assembly. Perhaps the owner has not even noticed that their frame, etc. lacks the multiple Erfurt proofs. Again, trading would be nice if you have my parts and I have your parts. Since there are not too many artillery Lugers around, maybe there is some slight hope, especially if the parts were mixed in the US instead of in Germany.
