To start with why not get hold of the chassis and engine number then contact Morgan to check it out .Anyway of checking its history ie the owner and past owners from the who is selling it should give you some info . Ask for a look at any file on it and write down the details then look in the rear of miscellany and start your enquiry with the lads in there . Get in touch with a flat rad owner for details and e-mail photos . But remember thats 62 year ago so you can expect changes in some things.
