Vintage Classic Norton & Other Motorcycle Parts

I'm having a clear out and have a selection of various mostly Norton motorbike parts. Take a look at the pictures as what you see is what you'll get and form a big part of the description. There are various heads, barrels, gearbox casings, gear box, chains, sprockets, wheels, etc etc too much to list individually. I've checked what some of the parts sell for so this must be great value for the whole lot. I have no idea what models they are from, open to folks telling me, most of the heads & barrels have part numbers. Collection only and bring a good sized boot. £750 and open to sensible offers. Thanks for looking.
