Derk,

IIRC the British bridge classifcation sign had a rolled rim, the ones fitted to Canadian CMPs were just flat plate, with screw holes in different locations to fit them in the headlight aperture or on a different location. The former can be bought from various suppliers in the UK, Marcus Glenn springs to mind, the latter can be made by cutting it from sheet steel stock.

HTH,
Hanno
