Found on ebay a while back was a translation of a WWII-era German report on the Dornier P 232/3 design. This was a proposed derivative of the Dornier Do 335 fighter… while the Do 335 had a piston engine in the nose and another in the tail, the P 232/3 replaced the tail engine with a turbojet. This would have chewed through the fuel in a hell of a hurry, but it also would have increased top speed. Mixed propulsion fighters like this enjoyed a brief burst of popularity for a short span of years immediately following WWII, but apart from some prototypes nothing really came of them.
The ebay sale helpfully provided some good scans of some diagrams.
Great material, thanks!
