Ah Ha! Thanks Wojtek, I thought the colours looked familiar from somewhere, I saw the aircraft in a modelling magazine quite a few years ago; it caught my eye as Stretton is only a few miles from where I've lived for the last 18 years. Part of the airfield is still there, used by Shell research, but the M56 Motorway runs straight through it now! Strange seeing a model of a 'local' kite all the way across in Oz!
