I am not aware of any WWII Naval aviation training in Boulder, Colorado. Pre-Flight was on either coasts and then along the Gulf. Interestingly, I have yet to see any evidence of Naval aviators or aircrew using the Western five inch knife, the six inch yes.  

No problems.  Nice helmet.

Nice helmet

Thank you everyone for helping me. Why is this hand embroidered instead of machine made like a lot of others?

Hi to all and many thank's for your opinion's expert  (Blacksmith, Warguy, Manayunkman, Doyler) It's actually wonderful to have american thoughts.   I'm not sure to can afford this one. I am going to try.   Have a nice day   Dominique

I changed some words around when I googled and found this AI       

Dear Mr. Manayunkman," Please, what are you still talking about? Just an hour ago, I posted the following statement: Given the significance of this find, I have decided to take a bulletproof approach: The artifact is now being sent for detailed analysis to internationally recognized specialists in forensic textile expertise and early Cold War technology. This analysis will include microscopic examination of the fibers and comparison with the Aero Medical Laboratory project protocols to which these experts have access. In any case, thank you for your expert opinion and it will be my honor to inform you of the result. "Please, read the entire thread carefully. At this stage, the matter is already being handled by colleagues who truly understand the subject."

I thought I was the only one who did that.

Where does your information come from?   The tags in the shirt should prove your point but they don’t, the tags are those of a privately purchased shirt.   Unless you come up with the proper proof there is no longer a point in continuing.   The posters mind is set the he is right and we are wrong so what’s the point.   If the poster is correct we should be able research this but I’ve googled my face off and can find nothing about any special made shirt.   Show us the military specs for this shirt, you can’t because there aren’t any. We trust military specs not emotional conjecture.   You have to show rock solid proof, find the specs for this shirt and we will believe you   You can’t show anything good luck with your shirt, I’m out.

thank you, Rhscott. I truly appreciate that someone who is a real expert in military logistics, unit histories, and technical equipment details recognizes the significance of this thread.“
