Here's a nice original, genuine Vietnam vintage fatigue uniform patch for a Chief Enlisted Aircrewman in blue.  Research tells me that these blue patches superseded the olive green type.

This is a full sized patch.  The edges are folded under to be sewn directly to the uniform chest.

I'm selling a dozen or two of these patches and the odd one has a maker's stamp on the back.

Good luck bidding and thanks for looking at another auction from The Mighty Atom.
