U.S.A. Model 1917 "Eddystone"
This is a knife/sword bayonet manufactured beginning 1917 and was used on
several firearms to WWII.
They are very similar to their predecessors: the British P1907 (muzzle-ring is
closer to the blade rib and does not have U.S. markings) and the US/British
Model 1913/17 (has the same dimensions, but does not have the U.S. Ordnance Bomb
on the ricasso). The Model 1913/17 will interchange with the Model 1917 but not
with the P1907.
These were manufactured for the U.S. "Enfield" or "Eddystone" .303" caliber rifle
(not to be confused with the British No.1 SMLE series which accepts the British
Bayonet examples made in the U.S. are stamped with model date "1917" over the
manufacturer's stamp (in this case REMINGTON in a circle). Reverse is stamped
with the U.S. Military "ordnance bomb" (aka "flaming onion") logo above "U.S.";
to the left is an "eagle-head" over a date of manufacture (in this case 1929); to
the right is an "X" presumed to be a testing or proof mark (perhaps a bending test as
with the British counterpart).
Manufacturers were Remington and Winchester (the latter being quite scarce). Blade is
made of steel, grips are of wood with two horizontal grooves cut into the sides;
pommel will have an "oil-hole."
Scabbards were either green (olive-drab) fiberglass with steel throat or green leather
body with steel throat, drag, and belt hook.
