P.L.A. Railways, (Port of London Authority), very rare, Peacock 1952, 117pp, hard bound in blue cloth

6? x 4? oval ?BRISTOL TRAMWAYS CAR LICENSE? has the appearance of slate but I think it is zinc, the centre part has the number 153 formed inside an area filled with a red substance which could be crazed paint or wax, 2 screw holes, the misspelling (according to English usage) of ?LICENSE? is because this is the plate from a car made in the USA so American spelling has prevailed
