WW2 - Reference Books
This chart was made in 1989 and has approx 100 USN & USMC Squadron Patches pictured in color. I had used this quite a bit for patch identification. Its not brand new condition, but it does what you are going to buy it for. It is folded twice, has a few marks here and there, but it is still a nice looking patch chart. Sorry for the glare in the lower left corner.
