I see there is a Chipmunk thread running but at Burnaston we did the annuals on the University Air Squadrons. I think there were 2 or 3 UAS , Nottingham being one.
They had Chipmunk and Havards. They would arrive en masse in the Autumn and then an RAF Anson would arrive on a couple of trips to take the pilots back !
They would be overhauled during the winter and they would return to the UAS in the spring. They would be all neatly lined up on the tarmac on the appointed day and then the Anson would arrive!!
There would be over a dozen aircraft ( and not all would depart that day !!) The Harvards were started with Trolly/ack and as mentioned the Chipmunks all had Kaufman Cartridge Starters. The starter took a magazine which held 5/6 ?? cartridges and the noise and smoke was like a battlefield. Engineers ( they were a fixed group that did the RAF aircraft ) were rushing around changing the magazines. These cartridges provided endless apprentice projects in the summer evenings!!
