This a pic of my P14, which is essentially the same as an M17.
It was mentioned earlier that you should try and avoid chopping up a rifle that is in complete military trim. These are quiet valuable now and no doubt a mil collector/shooter would pay ou handsomly for it. The Winchesters are the rarest and most valuable. I have been shooting these for years and have owned a lot and I have never seen a Winy in full battle trim. I bought a sporterised one recently and it was a sniper, very rare. I gave it to a mate who restored it.
It will have a W in front of the serial numver if it is a Winchester, If it is a Winchester, look at the rear sight. If it has an adjuster knob atop the sight with a three pointed Mercedes style star, it is a sniper. Well over a million M17's were made, only 2001 Winchester snipers were made. Worth mega bucks!!
Ignore the rear sight, that is a volley sight, it is an additional sight, used in conjunction with this (extra) front sight for long range volleys.
The old farts that were running the armies at the time had a lot of old ideas, volley shooting was one of them. They also had a extra swivel at the front called a 'piling' swivel, which allowed three rifle to be neatly stood up in front of the tents. Modern warfare moved a lot quicker and they soon stopped that sort of nonsense.
Greta rifle, enjoy.
