If you have a chassis number it can get a plate. Touble is many have had the chassis plate removed to gain the scrappage bounty. Sadly I never worked out where this was stamped on the chassis, but I think like the Type 70 the front suspension head stock area locks favourite. Stuart holds a lot of records and a chassis number will put him warm on dating, though we can tell the model, A through to E, apart from fittings. So date is possible with proper pictorial evidence.
Anyway, you need to get hold of Stuart.
