They could have been switched during assembly as levers.Cables and other small parts came packaged in a box contained in the larger bike box. Almost every dealer I called on was at least a 500 club member with sales of Schwinn bikes above that number . When a number of bikes were being put togeather it would have been relatively easy to switch parts boxes or parts. I recall Letours as having the same partial assembly as Chicago bikes. Most Japanese imports were much more complete out of the box with levers and tape already fitted
