M4 Bayonet for M1 Carbine with Scabbard WWII

This is something I have been looking for for several years. It is a proper American made bayonet made during World War Two. The bayonet I have is a 1960s Japanes example.
This style of bayonet with a 6 and one half blade was used up until recently and is possibly still in use. The leather handle is unique to the M1 Carbine although there is a combat knife version.
