'Ello mush, got a new motor?

My friend Andrew bought a new Lancia.  I say new, it was built in 1937, and now it's being re-built by him.  He has form; he has re-built several Alvis cars, a BMW, and others, all pre-war models.  He's pretty good at this and it's just a hobby for him.  When it's done it will be good as new, the he'll sell it and start again with something else.
