Carlo Abarth, pre-war moto-racer on Belgian FN ?!

[webchef reKupnet]

Browsing through Wikipedia, my eye fell on this sentence;

"Famous pre-war racers associated with FN include Kicken, Flintermann, Lovinfosse, Lempereur, Sbaiz, De Grady, René Milhoux, Charlier, Pol Demeuter, Noir, Van Gent, Renier, S "Ginger" Wood, Wal L. Handley, Edward Mellors, and Abarth."

Anyone who has more info, like photos, exact type of bike, etc.?
As a Belgian motor-enthousiast, it would be fun to look out for the exact bike(s) he drove, and maybe put one in Guy's museum, within time...
