Good day;  My father (Charles "Chuck" Mandelin) was S-2 in 1970-71.  I am trying to locate an original Vietnam-era squadron patch to build a display to pass on to my kids (he passed many years ago).  The internet is full of fakes and crap.  If anyone has one they'd be willing to sell, please let me know; or, if anyone can show me what the original looks like so I know what to look for, that'd be great, too.
