M7 Bayonet and Sharpening Sheath
 
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 Bayonets look unused. May have a few scratches on blade from transport and age, or dings around screw points but otherwise GOOD condition.  Whole bayonet measures just under 12 inches in length.
The Sheath is a sharpening sheath-it will scratch the blade with each use 
due to the sharpening effects.
