Ya I like those and my 1917 Enfield is one of my favorite rifles mostly for the history and for the awesome price of $160 less than 2 yrs ago. I also love the other WWI stuff I have such as a 1903 Springfield bayonet in scabbard, doughboy helmet, and a belt with canteen, cup, cover and a mag pouch. I did have 2 of the 1917 bolo knives as well. I also have a german demag bayonet, a real one that cost me more than my 1917 rifle. Unfortunately, I somehow unluckily missed out on my great uncles 1917 artillery luger with shoulder stock.
There is just something about great war artifacts, no matter what they are. Its hard to explain. Between their age, the fact that the US was not involved for that long and that it seems much less popular than the civil war or WWII, its just more appealing to me in many ways but my favorite war (how about that as an oxymoron) is still WWII.
