*The American Leader movements from this run are 21 Jewel Hunting case movements.
Somewhere between the 17187568 American Leader and the 17188018 CPR would mark the beginning of the CPRs.  The assumption is being made that that number is 17188001.  Likewise, then end of the run is assumed to be 17188300.  This would mean a production figure of 300.
