SINCE WE ARE ON USMC KOREAN WAR SPECIFIC HBT UTILITY UNIFORMS,  HERE ARE PICTURES OF TWO MINT UNISSUED, NEW OLD STOCK, 1950-1951 USMC P41 HBT UTILITY UNIFORMS (SHIRTS WITH MATCHING TROUSERS).   EASILY IDENTIFIED BY THEIR MINT GREEN COLOR SHADE AND ROUNDED OFF POCKET BOTTOMS AND THEIR GUN METAL COLORED U.S. MARINE CORPS DONUT BUTTONS. SOME WILL HAVE THE MFG MARKINGS ON THE INSIDE OF SHIRT OR TROUSERS, SO FAR I HAVE JUST SEEN:  BLUE ANCHOR OVERALL CO INC,  CONTRACT No. M-59154 OR M-XXXXX (SOME OTHER NUMBER).   1ST MATCHED UNIFORM SET

Agreed.  I think they aren’t period insignia at all.  In a nutshell I think someone took a later set of dies and then worked hard to make many sets of dolphins from them that “look 1940s” from the reverse.     I have an unmarked enlisted set that looks cheaply stamped in my junk box of insignia that are clearly post 1940s.  I’d guess 60s or 70s from the finish.   Not to mention I’ve never seen an attributed set in any grouping for over 20 years of looking,  plus there’s more of these available sale than good US- made AMICO ones.., which doesn’t add up for supposedly Theater made insignia.  Yes I know they got featured in a certain book,  but that doesn’t really mean anything beyond one author’s interpretation of information available at that time.

Cool! No suspenders, but sewn on rank! I've never seen any with sewn on rank. Congrats!

It was actually Alain Batens who put me in contact with René Leduc after I had told him I was looking for a WW2 Jeep. I had met Alain through my my father's brother (my uncle) as they had studied together in Antwerp in the 1960s and remained lifelong friends 

2 suspension rings is indicative of Navy issue.

SECOND M1953 SHIRT FROM ABOVE PICTURES WITH ITS MATCHING COLOR/SHADE & PERIOD M1953 TROUSERS    

I will study that link. Thank you.

Will add your skull crusher has the point blunted/removed. This was a fairly common practice when caried as it would cause injuries to the hand when carried 

The CG36500 underway. Next is one of my cousins at the helm in 1968, shortly before 36500 was decommissioned. Note the block of wood chocked against the throttle, because it kept slipping off its setting.
