I'm afraid I know very little of Mr. Capon - Other than to say that I have a wooden box that contains some of his models AND some of the 'Jigs' used to make his 'Krusader'. Plenty of pictures!
P Capon holds 'Krusader' at Old Warden in 1983. Denis Fairlie - 1936 Wakefield Team member looks on.
There follows many pictures of another model from the 'Capon' box. I assume a somewhat later design in view of the electronics!
