In answer to your question wem I believe there is a small and dedicated following for VN era militaria. There are also some fairly dedicated dealer sites which supply VN/Indochina stuff. You would probably be suprised at the prices for some of the high end gear especially in regards to SF/SOG, ARVN rangers, etc. Some of the badges alone for Recon Teams/Hatchet Forces can range around the $400 - $450 mark. There really is a lot to get your teeth into with just the American stuff, let alone other nations Cambodia/Australia/Laos not to mention North Vietnam/Viet Cong, French from the first Indochina war. There are also lots of variations for camo, duck hunter/tiger stripes all with their own different types/variations/weights Jungle kit comes in models 1st/2nd/3rd, nonripstop/ripstop. It is really very interesting stuff, the list goes on. I am by no means an expert and am learning as I go along. I am lucky enough to have a know a guy in the UK to answer my bone questions for me (which are alot) It would be really interesting to hear from any of the old salts, units served in, etc although I am well aware that it is deeply personal stuff
