Hello , I do free ID help of WW-2 era USMC and USN flying unit emblems, if you have any that you need help with please contact me as I enjoy helping do this if possible, I've been researching USMC/USN/USAAF patches of this era for over 25 years.
I'm also an artist of leather flying unit patches of this era.
Happy history hunting !!!!!!!
