Hi Michael, It seems to me that the value of these items would be what it would cost you to replace them (or with something similar) should they be destroyed or stolen. This same logic is used to evaluate natural history collections. What would it cost to send out a collector into the field to replicate what was lost? If you can purchase a similar item at a military scrap seller, then the value would be what the scrap price is plus any time spent shopping and costs for crating and shipping. If they can be found at military surplus stores- the same would apply- your price, plus your time and travel and shipping. It never ceases to amaze me that the military can spend millions on something and sell it later for 10 cents a pound. When I was a teenager our science teacher took us to a military scrap seller and we purchased a radar jamming bomb for about $5. It was pretty cheap thrills taking it apart.
