There are several places on the Internet that advertise they can make "military patches". The one I got a few months back was never used; and is clearly not 2 or 3 decades old. As soon as I got it, I immediately concluded it was/is a reproduction. This same guy over the past several months has also sold patches for the 57th, 170th, and 189th AHC's, and some others as well (1st Avn Bgd, etc). I think he should at least acknowledge the provenance.
