Hubcap centre emblem needed

[Steve Phillips]

Hi everyone

I wonder if any of you can help,
I have a customers Bristol in and one of the jobs is re chroming. I have good hubcaps that can be chromed but I'm missing a centre emblem, as in the attached picture.
I wondered if anyone had one I could buy?
Or
Knew of anywhere where I could get one?
Or
Know if they were used on any other make of car?
Many thanks
Steve
