A Nice WWI US Brass Knuckle Trench Knife By LF&C

A really nice WWI US brass knuckle trench knife by L.F.&C. The handle is marked L.F.&C. The blade is unmarked and still has most of its bluing. It has from what I am able to gather the rarer leather sheath which is pretty stiff and has some markings at the top that I'm not able to read. Over all a really nice knife!
