These measure 1" square on each,brass on blue wool, 100% authentic and VERY rare. These came from a large collection of a gentleman who was a Tech Rep pilot and Quiet Bird member. I will be selling off the lot in the next week so stay tuned. Dont miss out as these NEVER come up for sale EVER good luck.
