I have all kinds of "stuff" that I brought back from Vietnam. Every time I visit a war-type museum I ask if anyone is interested and have never found much interest. "send us a list and pictures and we'll let you know." is the usual reply. I know the plan is to donate everything, including the planes and tanks but???? I think ebay and get what you can is probably more realistic. As to what they are worth, that depends on many factors, quality, detail, kit, scratch-built, rareness, etc. I've seen built models on ebay for $10 - $5,000
