Original WW2 M3 SMG .45 Cal grease gun magazine pouch as used by the US Army and the USMC. It appears to have very little use and is in excellent condition. 

Designed to carry eight 30 round .45cal magazines. Constructed of heavy OD Green water resistant canvas, each case comes with a steel lift-the-dot type snap, heavy web shoulder strap and integral web belt loop all heavily stitched for rugged structural support.

All pouches are from a warehouse and might have minor storage wear (hence, listed as 'used') as they were manufactured over 70 years ago. Listed as "used” mostly due to their age, but I doubt they have been used before.
