Hello Mrs Flatchat
Lovely looking car
I know this is not the exact wheel you are looking for BUT
If you look up "PS Engineering" in the search gallery section you will see pages from a catalogue for a company "PS Engineering" in LA California.
The owner Phil makes period correct wheels for many cars and in there is a wheel very similar to what you are looking for. If you are interested email me I can give you his contact details.
