Nortons - General

I have a knackered grey faced tacho 1964/5. It might rebuild OK but i cant find a supplier of parts, particularly the face for the 2:1 ratio clock. Can anyone help?

This is from page 85 of the Edgar Franks 1949 Norton Motorcycle Maintenance and Repair.

BBC1 today 25/5/25: someone turned up with 2 Featherbed Manx frames.  One still in Rex McCandless's assembly jig.  Plus steel templates to bend the tubes to correct curvature.  Antiques Road Show, final item...see BBC iPlayer

I'm sure much has been written about this topic down the years - but I'd like to revive it after a recent comment on a Commando thread.

I have some handlebars on my Mk2 850 Commando that have makers numbers stamped on them. I'm trying to find another set of bars the same but no amount of googling is turning anything up. Can anybody tell me who might have made these?

Just been sent this picture, what bike is it?   I suspect some AI generated nonsense.  I await enlightenment.

I recently bought a front mudguard at Kempton, it was labelled (well masking tape and marker pen) as ES2. It looked about right for a Norton, good weight and not much rust. When I got home, I gave it a more detailed check.

Can someone tell me the size of the clutch adjusting screw in the clutch outer pressure plate?
I suspect 9/16" x 16TPI.
My outer cover needs work and I must decide how to do it.

I see all the Norton tanks on the Indian supplied tanks have the word 'Norton' blanked off.  This means we can't see the transfer.  Is this the dead hand of the new holder of the company name, demanding royalties from vintage parts suppliers?  So

Hi all. I am wondering if anyone has more than a passing acquaintance with AMC gearboxes. My bike will not change down from top, or I think from 3rd to 2nd. The lever moves but no change happens.
