It's Ken Wallis not Wallace! There's another proponent used to live near Lambourne Berks, but I can't recall his name; his were Campbell Autogyros. Both he and Ken have done trials at Farnborough for various reasons.
Years ago, CSE were thinking of importing a sophisticated american design (Umbaugh?) which had an enclosed cabin with two seats and a 'jump' takeoff facility; when you powered up the rotor for pre-spin takeoff, you were able to engage a sort of collective pitch system giving the rotor blades positive angle of attack for a short while thus allowing a vertical takeoff rather than needing a short ground run.
