Tks, ...for the infoPresumably, you mean the drum sprocket, not "hub"?
"062194" appears to be the casting number for the rear drum cush sprocket but the actual drum sprocket part number is 062764.

Means nothing to me. Where have you seen that?
Kinda thought that after I posted..tksYes, I just traced the /VB78/ to an ebay seller that has other items marked with /VB78/ (below) and seems to be the seller's own code, perhaps the stock number of the bike the parts were removed from because it isn't a Norton number.

And for parts....
Quite right... not bad for those too...!
What's meant to be wrong with the Norvil ones? I had one on for years with no problem or what I consider to be wear on the teeth.
Cast Iron vs Cast steel of original, if yours is wearing well then its cast steel.
Bloomin' eck! Cast iron wouldn't be any good. I can't check as it went on fleabay but it looked as new when I swapped it for one of Doms that came with his hub.
