Jerry- been a tad offline here.... promised email is as follows:

ebay often has recently out-of-Nam Swamp Rat patches... fairly authentic, and not badly priced.. just click the EBAY SEARCH button at the top of this page.....

someone here might have an original, though..
dunno if to spare, though...
but-
the patch on his jacket resembers the 282nd AHC, I think... I'll research that.. Black Cats, I think they were...

someone here knows-

thanks,

cooling off in Virginia- seventy overnight !!! YES !!!
