Drifting the thread just a bit, might I ask if that Prentice was subsequently flown to South Africa via Khormaksar?
I remember reading a story in 'Meccano Magazine' in about 1960 of a Prentice being flown to Australia with only a 4 channel set and no spare crystals; didn't even have 121.5.
Can't remember the reg but the aircraft was named 'Koomela'.
