A few years ago, I found a wonderful 1930s Black/silver metal GB plate at a local antique centre.
Mounted on a bumper bracket, we’ve used this on all our recent visits to France, with no problems.
Not sure what we’ll do on our next trip, but I’m not keen on sticking anything to the rear bodywork of the 4/4.
