Original WWI US Trench knife and scabbard. The exterior of the knuckle guard is maker stamped "LF&C." with 1917 date.  The blued blade has runner marks from the scabbard. The wood handle is excellent with no cracks or chips. The original scabbard is correctly stamped "MS" on the upper metal band. The leather center is completely in tact as well and stamped "Jewell 1918". Very nice piece that presents well.
