BTW, in the UK
# is _never_ called "pound". "Hash" is the most usual
BT tend
to call it 'square'. Confused me the first time I heard it.
I've not met that, although I have, come to think of it, met
"Octothorpe" (I think it was in "Understanding Telephone
Electronics").
Ironically, the New Scientist article about digital exchanges (1981?)
that called it "hatch" printed it as a square...
(FWIW, "-thorpe" is often found as a placename element in the Danelaw -
parts of England officially occupied by Vikings before the Norman
conquest - and it means village, equivalent to German "Dorf".)
Cutting the extra 2 slots in the cam would be quite
easy with a dividing
head (no, I'm not offering to do it, right :-)). The problem is finding
an arrangement of 12 holes in the dial plate that (a) allows you to dial
all of them and (b) maintains the required pause between letting go of the
dial and sending the first pulse (this is part of the spec).
You're in danger of making the same mistake as Sam. Remember the pulses
only go to my counter chip, not to the exchange, so the pause after
letting go of the dial is not essential. That said, it is useful if
your finger is shaking as you dial...
My idea was to have a moveable finger stop like on some smaller dials.
This would normally sit quite close to the 1 position, leaving room for
* and # after the zero, but when you dialled against it it would be
pushed to its conventional rest position.

PS I'm off on holiday for a week. I won't (intentionally) set the list
to Postpone, but I probably won't read all the messages...
