My one piece of insight to share on #471 is that if you look at the red
numbers, they are different by 4 or 5 from the adjacent red numbers.
With the exception of 9 and 0 (which are either 1 or 9 apart, depending
on how you look at it.)

My gut feeling is that this dial is for remapping the 0-9 digits such
that adjacent digits do not come out near each other in the remap,
maybe something like a grey code. The 20-tooth cog and the
microswitch-style rider look like something out of a phone
pulse-switching system, although what kind of stepper switch they might
control I still do not fathom.
