France 405th Regiment Sleeve Insignia - 1950's/60's
Unsure of date or what actual unit this badge is for, but is sleeve insignia to the French 405th.
It appears to have some age, but bright color and just two moth nips under the "4" in "405" and on the lower right edge. There is also some moth grazing top green.
A single rank chevron has been added to above and back.
Behind are 5 metal hooks, for attachment to uniform
