Try this company https://www.dugout-memories.com/capsteam.html.  Not sure they will make a custom vintage cap for you.  They seem to just have a stock of vintage team caps available.  Might be worth a try though.  Cooperstown Ballcap Company used to make any custom cap you wanted but they have been out of business for a few years now.

Unless the number is listed in the GO, it would be almost impossible. 

Thanks for posting. Examples of these types of covers from WWII are fairly common, but from the Korean War they are scarcer. Part of the reason was the reduced number of casualties and the shorter duration of the war.   Kurt

My guess is these came from the CBI.  The OWI worked with the military to distribute news, magazines (like the CBI Roundup), and radio broadcasts directly to the soldiers serving in the jungles and mountains of Burma and India.

Anyone know who sells the Blue USN baseball cap of WW2 that has no adjustment band at the back with the green lined cap peak. Eastman did do them but no longer and At the front had them as well but the last batch gone. I had a Red cap from Eastman well made but looking for a blue one.

Great shot of those large "fish float" type helmet nets.

Thank you MC 43. 

Just saw the posting in tefrence to another U.S.N. M1 with simular markings. Here is my fsfb. Great information.  This forum never fails to amaze me. Enjoy

That's a cool book because it chronicles the story of the Eagle Squadrons in full.
