Just a thought could it possibly be a modified Luton LA.3 Minor fitted with an Anzani (British/Luton) 35 h.p. Vee Twin.

https://nelsam.org.uk/Exhibits/Search/?search=G-AFUG. I have been through Arthur W.J.G. Ord-Hume's book British Light Aeroplanes Their Evolution, Develpment and Perfection 1920-1940 and can find no reference to this aircraft.
Alec S C Lumcden in his book "British Piston Aero-Engines and their Aircraft" lists the Anzani engines on page 62. Aircraft listed under the Azani (British) 35 hp Vee Twin are the ANEC I,IA and II; Bristol Prier-Dickson and the Hawker Cygnet and for the Anzai (British/Luton) 35hp Vee Twin the Luton Buzzard I & II , Luton LA4A Minor and the Migner HM 14 Pou du Ciel.
