I just saw this but I my first take was the same as the later posts. The butt is short and weird and the finish doesn't match the rest of the gun. My guess was the butt ws whacked off and a really weird buttplate added, then the butt back of the PG sanded and refinished. It looks smoother, more polished and newer than the rest. The fore end was probably just whacked off. I have owned quite a few original Mannlichers and never had a trigger that looked like that. It resembles an Enfield in many ways.
