Danny:-
Reg Lewen ? (couldn't have confused him with Reg Levy, Sir ?)
Indeed I could, Danny. Mea Culpa, I remembered his PPRuNe ID, Regle, but misremembered that it stood for Reg Levy and not Lewin as I posted. I recently bought a shirt made by a firm with the latter name, so perhaps I got confused with that. Typically, you had no such senior moment!
