Hi GttC,
Yes I am sure that an engine was supplied and it is possible that it had been in the Fouga 3-KE, but I did not see it in the Noratlas. The log book for 221 AKA 3-KE specifically stated that it was less engines. It was a long practice to allocate serials to aircraft relegated and or procured for TTS, going back to the Hurricanes these were in the "A" series eg A3 etc.
All the best,
Tony K
