M7 Bayonet
No maker's mark. Only part numbers inside grip. 
Grip numbers (11010069) lead to NSN: 1005-00-051-3608 dates back over 30 years ago (before 1995)
 
These look unused. May have a few scratches on blade from transport, but otherwise GREAT condition.  Whole bayonet measures just under 12 inches in length.
 
NO SHEATH.
