There are some great subjects, some of which Airfix have done in days gone by in 1/72 scale, that would be very well received as new tools in 1/48 scale. I think Airfix would be on a winner with a 1/48 Fairey Battle, 1/48 Westland Scout, 1/48 DHC Beaver. And how about a 1/48 Auster AOP 9? The only game that was ever in town was the now almost impossible to come by Hallam-vac vacformed model and a 1/72 Armstrong Whitworth Argosy, Blackburn Beverley and 1/48 Saunders Roe Skeeter. As you can see I am biased towards the 1950s/60s stuff in British RAF/Army use but these aircraft were part of our aviation heritage and, in the case of the Westland Scout, the last helicopter ever built using all British components. I can only dream, I suppose.
