Theater made of cotton banding with white wool letters.
I bought this from an old collection, one that had just about every armband that you could imagine. I have not seen this one before, and going only on what I was told by the collector. The construction is a salmon colored cotton, with a white linen cotton; sewn with red cotton thread, The letters are sewn down white wool. Measures just over 3 1/2 inches. Would have had a safety pin for holding it in place.
Air Ordnance works for me until absolute verification is establish. Its real, and original.
