hello everyone. I just got this jacket with wool liner and cant find any information on this patch. I was told its a 1950s jacket but don't know if this is true. its still in great condition. I'm hoping somebody can help me figure out any additional information on this jacket. im wondering its age, the patch, and an estimation on its value. anything would help me greatly as I looked all over the internet and cant seem to find anything on it. thank you!

Its very nice mate, some better photos would be nice though .
Id dated it 1958/59 Early 1st model L-2b . MIL-J-7448A .
Interior colour Grey Silver / Later models had a Orange liner
USAF emblem on L/H shoulder looks good , also later model ones are a darker shade of olive.
Thumbs up all round from me

I forgot to mention the Beautiful Flight patch is 9th Tactical Reconnaissance Squadron USAF so fits in lovely in the whole thing.
Date wise.
Its grouse !
