Just out of curiousity, has anyone tracked down the (many) patent numbers associated with Norton motorcycles ? - or any other brand for that matter.

Patent numbers and badges abound - but what ddo they mean, and how are such things described and illustrated.
Anyone know the patent number for a slimline frame, for example.
frame, being more recent can actually be found online. But the earlier stuff ?
Do you need a Readers Ticket, and visit the British Library for the full chapter and verse ?
