This showed up here the other day, it's a Crosley CIBA block with some sort of generator attached to the bellhousing and aircraft-style ignition wires. I believe it's an APU from a cold-war era bomber. I haven't been able to find any information on it. Sadly, the manifolds are missing. There's no starter; I suspect you started it by applying power to the generator. Is there much interest in saving it as-is or should I just part it out?
