The following might help towards an answer:- A.H. - Aircraft Handler ASP - Air Stores Park Ammunition Sub-Park Anti-Submarine Patrol PTC - Primary Training centre PDC - Practice depth Charge MU - Maintenance Brummy I don't know the story about the Belgian Spitfires,but your friend is right some of the MUCH later versions of the Spitfire did indeed have "Clipped Wings".I don't know which Mk No's they were as i can't find my Spifire Book at the moment.Some of the last versions of the Spitfire even had "Bubble" canopies as well. If i manage to find my book i'l post the information on here,but i'm positive that someone will have answered your query in much greater detail by then. Stephen
