Hi Mr. Green 
Did not recognize it on the first pic. I think this is the Aircraft K by the Raduka Design Bureau (which alledgely had ties with the MiG Design Bureau). Aircraft K was built to speed up development of what later became called Cruise Missiles and as you remarked carried a pilot. It externally resembled the KS-1 Kometa (NATO Kennel) cruise missile. Aircraft K could take of under own power or was air-launched by a Tu-4. Seems 3 were built (K-1, K2 and K-3) and engine was a RD-500 (RR Derwent development). First flight 1951.
The Australians did a similar thing with the manned Pika version of the Jindivik (target) drone.
