In the red dot showed in the picture, after the two prototypes, the ON-OFF switch is missing?

Yes, and looking at the display screen the LEDs are missing too - it looks empty. So it seems to be a case model only with nothing inside.
.

Looking at that same "empty case" Red Dot HP35 in the picture, I notice now it has a grey rather than black x↔y key. The HP-35 in the auction that started this thread has a black x↔y as does the "front view" of the Red Dot on the museum page.

So, was a grey x↔y key a manufactured subvariant of the Red Dot? Or is this one in the picture of 6 merely some pre-production hack-up that didn't completely reflect the Red Dots that actually made it out the door? We can already see it has no display or power switch, so I'm a little suspicious of it.
