I've been toying with the idea of a long barreled P08, maybe with a forearm, but wasn't sure if I wanted to cut into a perfectly good P08 frame. In the meantime, I made a long barrel out of a Winchester Model 70 barrel in 30/06, re-chambered to 7.65 Parabellum, and turned to fit Mauser carbine rear & front sights. I couldn't decide between the FN M24/30 or the Argentine 1891 Cavalry carbine rear sight, but they're both the same ID so I took pics with both mounted. The front sight is the 1891 Argentine, without the hood. Extractor cut hasn't been made yet, which is why the toggle is sticking up.
Haven't decided if I'll taper the barrel more or leave it like it is...
