Actually the sites you found have a better copy of the original photo than I used!
However, if you had read the text a bit more attentively you would have seen that although a lot of the first site is Alf Baker, the AB in this case was Alf Beasley.
It was a Lea-Francis engine, which, although you may not have noticed it, is a common thread for several of my offerings.
I think that's solved it as I only asked where it was made and what the engine was.
Arthur Dent got the country; Pieter got the engine.
How can I award half a mark each
