Thanks David for replying to my post I did realise it would need a certificate to run it in public, but as I only plan on running it at home for my own pleasure I don't see it as a problem.
I have included some photos of the boiler in question.
It was purchased off Ebay from a guy who said it was from a house clearance and didn't know anything about it. so i thought I'd take a chance, not yet tested it myself yet but doesn't look bad. there were 2 for sale at the time, don't know who has the other one.
