I'll be in San Antonio, TX during the VHCMA gathering this next June, 2014 between the 18th and 22nd of the month. All three helicopter books will be available at a deep discount: "U.S. Army Helicopter Names In Vietnam", "Vietnam War Helicopter Art" and "Vietnam War Helicopter Art, Vol 2".
Also, I'll share what info I have on surviving VN War Army helicopters (approx 1,000) that are presently on display in public museums, military bases and memorial parks across the 50 states. I've compiled a database list which you can view and luckily can help identify an old in-country bird. Hope to see you there.
