Have you seen any of the post WW2 footage of the B29s being flown strait from the factories to the scrappers? Sad to see, but the war machine was going full tilt right up to the signing of the peace treaties...probably after, until confirmations.Lost in floods, fires, sold for scrap, plain discarded before anyone thought they were worth saving, etc. After WW2, we piled up hundreds of Zero fighter planes and burned them! Imagine what the value would be today for historians & collectors. As a kid, a pal found a WW1 German helmet in the local dump; bet lots of "rusty, useless old guns" were just abandoned and trashed.
