Austin RK rear number plate bracket

[Mike Costigan]

The ones I recall on my RKs were rivetted to the number plate with three rivets, similar to the Willie McKenzie repros but closer the end of the plate. They were Z-shaped so that the lamp stood proud of the number plate and provided the necessary illumination. I suspect the curved ones are probably a later development as the curve provides some springiness to the bracket and protects it better from breakage if the lamp is hit.
