G-AISA is a Tipsy Trainer 1, but it was first registered rather earlier than the date that you gave. it was built on the Slough Trading Estate in 1947 and was registered to the Tipsy Aircraft Co Ltd on 27.6.47, and flew for the Fairey Aviation Co Ltd until it was given to the Royal Naval Flying Club on 1st July 1949. It was later sold to the Armstrong Siddeley Flying Club at Bagington.
Nice looking aeroplane.
