Recently purchased at an auction from a building that it’s been setting in since 1969. I was told obviously it was repurposed after the war and use it some type of generator they worked on neon lighting possibly it was used for that, but it would’ve been a b29 bomber used to provide power when on the ground and engines idling. It also provided power for the emergency landing gear. My research show not many where made. Please look closely at pictures , do your own research, ask questions and If you need permission from your boss or significant other please do so before purchasing. It would have to picked up in person or shipped via freight on a pallet. So returning would be expensive. Sold as is no warranty. The engine turn over and has good compression. I believe it would run with some work.
