On the ab initio, or primary as the RAF called it, later elementary, the Tiger Moth was replaced by the Percival Prentice with the Chipmunk only going to the reserve schools and UAS's
Nos 4 and 5 FTS in Rhodesia went from Tiger Moth to Chipmunk in 1952, then on to Harvards. As a kid I used to play in the Tiger Moths in the dump at Heany.
