In 1968 when the Army switched from enlisted rank insignia on the sleeve to the collar they adopted pin on rank for most enlisted Soldiers, but because of concerns for safety in the event of a crash aircrew were mandated sew on ranks on their flight uniforms. This is an unused set of the E-6 ranks for that purpose.

These are not the later BDU ones, the background fabric shade is different in makeup and shade. The last photo shows these on top of a set of BDU ones to show the difference. It may be a poplin backing but I am not 100% certain the material so i am not going to make a claim for sure what it is.

Set shown is an example, I have multiple so may not be the exact one you get. These came from a closed surplsu store than had been around since the 1960's
