Some of these British quickies exist in private collections (like episodes of the Tod Slaughter & Patrick Barr "TV" series - in fact, never aired - "Inspector Morley Investigates"). The BFI also has a print of A GHOST FOR SALE (1954). I do have MAN IN THE MIRROR and also A PIECE OF CAKE (the last one from the BFI). Speaking of quota quickies, it's remarkable that none of the Tod Slaughter vehicles, from 1935 to 1946, is lost. The only exception being (for feature films) the 1937 DARBY AND JOAN, where he got a supporting part.
