I think I have a clue as to what all those extra parts inside the top half of the handle assembly on some Royal metal uprights (what you see in the diagram on this page in this HESCO parts catalog) were for: to keep the protective tubing (1-171333-000) over the short cord inside the top half of the handle from falling off.
On machines so equipped, these extra inside parts were mounted at where the top half of the handle meets with the bottom half. For household machines, these extra parts consisted of a metal cord anchor, lockwasher, hex nut and screw, while on the commercial machines this was done so using an extra inside strain relief (1-880304-000 for 3-wire SJT cords) with a metal washer over it.
In both cases, these extra inside parts holding down the protective tubing for the short cord were no longer used after mid-year 1984. I know, because my early 1985 Royal 880 definitely does not use these extra parts at where the top and bottom halves of the handle meet.
