To answer the OP's specific question, the change from foot starter to floor-mounted starter coincided with the change from 'bacon-slicer' unit to direct starter. In other words, all 'bacon-slicer' starters have the foot-operated switch. As Tony says, this change was made from chassis 99,001, and I believe Robert is also correct about the change to a ball-change lever occurring at the same time.
