Raleigh Hercules production
 

I am trying to ascertain the age of a 3 speed AMF Hercules that I recently acquired. It is a Raleigh Nottingham production bike. It wss hanging in a garage for many years and was covered in crud. When I cleaned the Stormy Archer hub it is an AW model stamped 2 10. When did Raleigh stop production of the Hercules brand in Nottingham?

That stamping on the hub is most likely 2 of 70. The stampings aren't always clear.
If it's AMF it's most likely mid sixties through early 70s.
These are versions of Raleigh frames and equipment. In AMFs case, they may even have NCC bits on them from China like brakes, seat and pedals.
