I'm aware of a bar through a z , to distinguish z from 2 and a slash
through 0 to distinguish zero from O. Anyone aware of an underscore
below v, to
presumably distinguish written v from u ?

Below suggests something else going on with 'u'
 
https://en.wikipedia.org/wiki/Regional_handwriting_variation
 
"The lowercase letters u and v — These letters have a common origin and
were once written according to the location in the word rather than the
sound. The v came first; the u originally had a loop extending to the
left and was only used to start words. All other locations for either u
or v were written with the latter. In Germany (especially southern
Germany), Austria and Switzerland, lowercase u is often written with a
horizontal stroke or swish over it (ū, ũ), to distinguish it from n."

I first took it to mean someone was empahasing the character was an
underscore in an email address , not a hyphen, but that was not the case.
So next attempt in the bouncing em train, will be a v in that position

It was not the sort of person, who would because he could , create an
valid email address with a conflated, by backspace, v and an underscore
into one character

It may be a convention from medical background, as plain v was correct
for this person of medical training.
Like a barred z comes from maths background, the slashed zero is pretty
universal

The other complication , mainland Europe uses a bar on 7 and then a
flick to the left at the top of the 1. Then in the UK that flicked 1 is
interpreted as 7, as we don't use the bar, but on the other hand , we
don't have a way of telling a 1 from a lower case l it would seem, other
than prehaps some people but an underscore to the 1

Is the Posi slotted? or is it like a Phillips cross-shape or is it like an Allen square shape or a hex?

I was on a job site where woodscrews were being put in and taken out an awful lot. Screw guns with Phillips magnetic screw heads were being used, which would involve many more rotations than with a non-powered Phillips head (which would take longer without the drills magnetic screw attachment). Otherwise, the non-screw gun Phillips would look ten times more worthless having done even near as much as a Phillips magnetic attachment for a cordless drill. '

I still have a couple SP23 irons, and several of the '60s version of
the 8200 guns. I wore out the internal threads on one SP23, that I
bought in 1970. Someone in the base's welding shop gave me some scrap
welding rods, so I saw, filed and tapped the brass to make my own tips.
They outlasted the plated copper tips.
 
I also have one of the SP series that's 175 watts.
 
I have some Xcelite tools from the '60s & 70s as well. I would
have more, but someone broke into my service truck decades go and took
most of my tools. I have one of the early 99SM kits, that was given to
me by a friend while I was in the Army. He laughed and gave me the
sealed package, then he said that he had watched me fix everything at
the radio & TV station with almost no tools for a full year, so he
wanted to make sure I had a nice set when I got home a week later. I've
had it for 42+ years, and I wore out the two hand reamers. :)

I keep thinking that touch-button (semiconductor), not push-button (mechanically actuated) is what you want. Touch button means there's no mechanically actuated "turn on" or "turn off" parts to get worn out.
 
Touch button just stays there motionless when you touch it and maybe lights-up or whatever, but it starts what you want without its own motion which could cause its own wear and tear. Buttons without wear and tear mechanical motion are offered by companies like "ideal", "little fuse", "keymatech", etc ...
