Jim,
Good point on the battle sight zero.
This set the rifle up for what is called grazing fire. You are right in that the grazing fire range of a rifle should hit between the knees and the shoulders of the average man.
Back in the day, it used to be called rolling fire and there were actually two different measurements for rolling fire. One against infantry and one against cavalry.
Bluey,
Any 1903 (I think the nomenclature is: Bayonet 1905) should work as well as any WW II bayonet for the M1 Garand. Most WWII M1 bayonets were cut down 1903 bayonets. The later M1 Garand bayonets will not work as they do not use a muzzle ring, but a protusion that fits into the M1's gas piston plug.
I think the stock in your first photo is an issue WWII replacement stock. It has the two reinforcing cross bolts common to this issue. I don't think that a nonissue stock or a hand made stock would have those.
Here is my most used Springfield. It is an M2 .22 rim fire training rifle. It is "as issued" and remains a very accurate rifle.
