WWII US Coast Guard Cook Ck1c White Navy Jumper

This one came by way of a Japanese vintage clothes dealer, a WWII USCG white jumper. belonging to a cook or steward, I bought this one at a risk as there is no way to research Coast Guard uniforms due to no USCG roster available online. I will update this post as soon as I find out more info about this Coast Guardsman.
