I really suck at seeing a good one. This one looks okay to me, but then again I haven't spent hours observing others or even seen one in person. Says it came from a family friend who was in the 4th marines but I heard so many stories that I rarely buy them anymore. Also said fixed bail but I see otherwise with the crooked bail. Stitching on side is apparently a field repair. Price is reasonable if indeed it's a world war 2 usmc cover. Has seaman liner.
