Tipsy Aircraft Ltd started up at London Air Park, Hanworth in 1937/38 and built 15 Tipsy Bs/Trainers/Trainer 1s before the war, and a further three in 1947/8 at new premises at Liverpool Road Trading Estate, Slough. Three incomplete cabin model Tipsy BCs were shipped from the Belgian factory at Gosselies to England and finished at Sherburn-in-Elmet in 1957 as Tipsy Belfairs, bearing the 'foody' registrations 'OXO, 'PIE and 'POD. Six Trainers and two Belfairs still exist in the UK.
