Jerzy Jankowski, Maximilian von Lerche and Francesco Mosca built at workshops of Moscov Aeronautical Society and airplane modeled after Bleriot aircraft with 50hp Gnome engine.

The Liverpool University MPAG bought the remains of Hatfield’s Puffin II in September 1969 and set about a redesign using the main wing structure and thr propellor from the Hatfield project.

The basic layout is a high wing aircraft with a pod-and-boom format fuselage. The wing is of metal structure with expanded polystyrene used to form the leading and trailing edge ribs and cross-pieces. Covering is of ‘Mellinex’. The wing is cranked upwards about mid-span. A conventional tail (tailplane and elevators, fin and rudder) is mounted on the end of a boom projecting from the lower half of the rear fuselage. The pilot is located in the extreme nose, in a totally enclosed canopy. A pusher propellor is mounted aft of the wing, above the boom. Single wheel undercarriage.

First flight was made at RAF Woodvale on 18 March 1972. It then went to Dulles Airport, Washington, USA, where it was exhibited at ‘Transpo 72’.

It is not thought to have flown much since its return, if at all,
