This distinctive shaped press steel wheel bearing dust cover is the one commonly fitted to 'cotton reel' type hubs - i.e. pre plunger (i.e rigid frame) rear hubs and those front hubs that had the 'bolt on' brake drum on all Norton models - it being slightly conical in shape
As with the other 'flat' type I produce, these are identical in shape and size to an original (as always - a NOS original was used as a pattern), except that rather than being in dull nickel plated steel, these are manufactured in stainless steel.
Although I normally sell them lightly blasted to give them the original satin (nickel plated) finish, they can be ordered here in their natural semi-polished stainless steel finish - which also looks nice.
The accompanying photo shows one of these conical bearing covers fitted to the 'cotton reel' type hub these were intended for, although the one in the photo is actually a 'dull' version (Item 0350), not the semi-polished type this listing describes
These are now a very rare item as whenever you find them at autojumbles - invariably they will have one of the tags broken off!
