WWII USMC Corporal Ship's Detachment

I like this one, but it slipped through my fingers a few days ago. This is a WWII USMC Marine Ship's Detachment uniform with the classic seahorse patch on the sleeve. I've always loved these ship detachment jackets as the patch is seen worn on the Marines on the deck of the USS Missouri during the signing of the surrender of Japan in 1945 as well as they represent the traditional role of the Marine ship components on Navy ships.
