WWII Bosun late 1942, believe this is a Navy Publicity photo of sorts

139th Airborne Engineer Battalion no?   Here is one. https://www.flakweasel.com/product-page/ww2-us-army-oval-139-airborne-engineer-battalion   Anfd one in this topic. https://www.usmilitariaforum.com/forums/index.php?/topic/404172-17th-ab-wool-shirt-with-wings-and-badge/  

I have aquired a bayonet that I can only believe now is an M5 style(?). The only marking is on the pommel 6F433 or GF433. There is nothing on the crossguard so I do not think it is a military issue as it is missing any manufacturer markings except for what I already noticed and the black coating is not present so the grips are a dull aluminum finish. 

That is a killer grouping!  LOVED looking at everything.  

Nice pistol.  I once had the earliest serial number pistols of this model that I have seen.  Colt started out with 15,000.  I forgot the exact number, but mine was something like 15,3xx.  It would have been made circa 1850 and likely went west for the Gold Rush.  I regretfully had to sell it later. Nice piece of history...

He hasn't logged on since September 2023, unfortunately   He may have sold it, it was posted on Instagram in 2024: https://www.instagram.com/p/DBrFr_AuKJk/ 

Steve, thanks for your reply, yes it seems to my mind that hanging the pistol by a leather thong would not be very hard wearing, they obviously thought it the possible answer in order to produce enough for a trial. Kurt

Thanks, I found it about 30 years ago at an estate sale in San Diego.  jim

Thanks, Obx. I appreciated the additonal information.

Nice helmet. You can buy an NOS webbing tie for the liner pretty cheap and you should be good to go.
