As far as I am aware there is no 1/32nd scale model of the MG Midget/AH Sprite.

There is a Lindberg AH Sprite kit that is supposed to be to this scale but these photos show that it isn't.

I'm not sure if this sprite will be built. It is on a Scalextric Mini Clubman chassis which has the perfect wheelbase and also is narrow enough that the axles can be shortened so that the wheels will not have to stick out as they do in these pictures.

.The best chassis I have found for a scale model of the sprite is the Reprotec Seat/Fiat 600. Not only is the wheel base and the axle width correct but the wheels and tyres are the right size as well. The chrome center of the wheels can be popped out and the hubcaps from the Airfix kit fitted for a perfect finish.
