Name:	Republic of Korea M4 Plastic Handle Bayonet
Value:	$*   *Value Help*
Total Length:	~11 3/16"
Production Period:
Info:	The blade does not have a 90-degree back cut to it.  It has the 1944-45 production style guard which is  secured by a bent  metal bar passing through the tang.    The construction of this area seems poor.  The two plastic grips have the numbers "7266828" & "7" on one, and the other "7266827     H6".  I do not believe these to be original. The latch plate has  the dimple stamp on it and uses solid  pins to hold the latch plates in place.  With the grips off the latch plate is really loose. No idea what the stamp means, but I'm told its Korean.

Total Length:	~ 11 5/16"
Production Period:	1956 - ??
Info:	The blade has a 90-degree back cut to it.  It has the 1944-45 production style guard which is  secured by a bent  metal bar passing through the tang.   The blade side of the guard is marked with a winged  anchor with a superimposed star and two unidentified  small marks, while the back side of the guard is marked  with the letters K.L. enclosed in a diamond shaped device. The two plastic grips have the a backwards "2" & "5" molded on them.  The grips are held together by two screws that are 4/5 threaded. The latch plate has  the SP stamp & "8  2  A" on it.  It uses solid  pins to hold the latch plates in place.   No idea what the stamp means, but I'm told its Korean. I've been told the anchor in pic 3 indicates its South Korean.  But I cannot verify anything on this bayonet yet. The latch plates have the SP stamping on it, which contradicts that its Korean made.
