Source of UK 1930s GRP Body?

[ggdrew]

I want to build a competition car with a light GRP shell based on a small 1930s saloon/sedan. The small size requirement means that UK manufacturer design will be best for me (e.g. Austin, Morris).
I've googled but can't identify any UK-based source of a small 1930s UK GRP body.

Any suggestions or leads that I can follow-up would be appreciated

Thanks in advance
