Guess where John Barnett got his start from? I Have some of the original manuals from the Schwinn School, Very nice drawings for basic parts.
 
Did you know that back in the Old Days a budding young "Schwinn-approved" mechanic, as part of passing his final training, had to be able to take apart a Sturmey 3-speed hub and put it back together without using the manual?
