U.S. WW1 Trench Knife 1918

[Deaf_Smith]

I was at this pawn shop and found what I believe is an original WW1 1918 trench knife.

Note the guard is bent a bit... I presume it was altered as they tend to be strait.

Now is this legit? I know the sheath was made for a WW2 trench knife (almost an M1 Carbine bayonet but with no ring or lug.)

They are asking $850 for both the knife and the sheath.

Opinions?

thanks!

Also notice the guard is bent backward.. some of the other original ones I've seen on the net have them bent forward or not bent at all!
Do they vary?
