i think this may be an army mess knife, but i am not sure. hoping some of you guys can help me with it. the overall length is 7.25 inches, with the blade using 3.75 of that. on one side of the handle, lengthwise, it has U.S. on the other, horizontally at the blade end, it has LF&C 1917 LF&C manufactured knives for the military, but i have been unable to find one like this......it appears to be an aluminum handle with a steel blade. is 1917 the date of the knife? the company? did they use aluminum for this purpose in 1917? it was in a mess tin that i bought at auction, but it doesn't match the other utensils that were there. i bought a lot of 3 or 4, and this knife is not matched in any of them. thanks.
