I'll add to this thread since it has the pictures. The rim is stated as being an S-7 so the next question, is the Schwinn Tubular S-7 stamped off to one side of the rim or in the center? Reason I ask is, this 415 model Torpedo hub production was 1962 - 1984. I can't say if Schwinn used these much later down the road or not but I couldn't find any info or Schwinn examples equipped with the Torpedo hub, just the Schwinn Approved Austrian 3 speed hub during Sturmys issues. So the rear wheel or possibly just the hub has been swapped out. Also check your shifter to see if it's mated to the Torpedo hub or a different make hub.
