Lovely, original Norton Model 18 flat tanker from 1927. 500cc OHV.
Correct numbers for frame and engine as confirmed in the factory records. Also the correct Sturmey Archer CS gearbox with the correct number as confirmed in the factory records. The CS gearbox is close ratio, having a CR stamping on top of the gearbox shell. The engine number is also stamped on the cylinder flange.

Dispatched on the 3rd of March 1927 to dealers “Crow Brothers” in Surrey, UK.
A rare, two letter/3 digit registration number as currently fitted to the Model 18 has been retained on the V5 accompanying the bike.

The Model 18 retains most of the original paint, and I think it deserves to be left as is but I will leave that decision to the next owner.

The Model 18 is very complete and in good unmolested condition. The bike has to be seen in the flesh to be fully appreciated, but it is remarkably solid. No threads are chewed, only light surface rust in places, no excessive play in the front fork, the Enfield rear brake and front brake are complete and functioning.

Engine and gearbox will need to be taken apart and gone over, but are in good condition. Cams/camwheels/camfollowers in very good condition, no teeth are chipped. Engine turns over smoothly. Gearbox feels tight. Sturmey Archer clutch is complete and in good condition.
With competent hands, this Norton flat tanker will be up and running again with little effort.

Lots of new parts purchased:

New rockers (newly manufactured, very good quality)
Pushrods + end caps
New valve springs, inner + outer (newly manufactured to original pattern)
New pushrod springs (newly manufactured to original pattern)
New kick start return spring (newly manufactured to original pattern)
New Gear selector spring (newly manufactured to original pattern)
Enfield rear hub cush cover + bolts (newly manufactured to original pattern)
NOS Hoffmann main bearing (impossible and expensive to find)
Oil pipe Y shape (nickel plated)
Inverted levers (nickel plated).
Spare CAV magneto.

Exhaust pipe, straight through, newly manufactured to original pattern.
New (old) exhaust rose nut.

The only parts missing are:
Best & Lloyd oilpump body (the internals are in good condition). The Mazac alloy on the original pump has cracked as is very common. A new replica Best & Lloyd oil pump body can be bought online with Vintage Replica in the Czech Republic.
Piston (I may be able to help)
