I think KP could very well be correct about the RH switch being 'transitional' because these sort of minor changes were typical for Japanese new model motorcycles during early production phases in an effort to get as many units off the line and into the retail market.
When the manufacturer of the switches ran out of pointerless kill knobs and still had unmarked bodies, they simply started putting knobs with pointers on unmarked bodies until they ran out of unmarked bodies.
And, if i recall correctly, kill knob removal requires dismantling the switch to replace the knob which takes time, effort and manual dexterity. Anything's possible in an owner's attempt to keep a bike on the road, so the knob could have been replaced. Seems unlikely a kill knob would break, though unless switch was left out in the weather. Does your kill knob look nice and shiny compared to the rest of the switch or does all have a matching patina ? I would tend to go with KP, unless you can find evidence the knob with pointer is not correct for unmarked body or someone changed it out, keep as is.
Cannot remember if the kill knob has a part number of it's own. i do remember the turn and hi/lo knobs have part numbers.
Would be good to get Andy Morris or Chris Rushton's opinion(s) on this.
Also, assuming your switch is original, this could be worthwhile documenting in "Production Models." i.e., "vin 609 noted to have kill knob with pointer and unmarked switch body."
Good catch "bojje" !
It would be really nice if all who post on BB use their name, so we can get to know each other more.
