The Adams brothers?

Edward Brothers?

Neither Adams nor Edwards brothers. British, and from the East End of London, and not widely known outside the specialist world of GRP body makers.

Sorry. Nowhere near.

It's a Convair S frame, used with the Excell body shell (we've had the complete car as a puzzle before)

I'm sad to say that the old "go-to" site for 50's specials has gone under.

Yay ! Correct.  Made by Terry and Clive Wren, similar to the Tojeiro frame, and could take a variety of engines. The front suspension was from an Austin (Nash) Matropolitan. It's quite possible that the engine in the photo is a BMC "B" series.

Yes, I miss "that" site too.
