I assume that Tony has, or has access to, a precision milling machine.
It might not even need an automill. At the very least for the purposes of prototyping,
it should be possible to carve some of the wards by hand with a Dremel. I've done
that
for a couple of mechanisms I've restored over the years, and if you don't mind
taking
two or three tries to get one that fits right it's doable.
The rear picture shows that it is not a fully
paracentric keyway. (where
"ridges" and "valleys" of the milling of the keyway would cross the
center
line, making it impossible to insert a very thin flat piece of metal)
Ooh - good catch! That's a really good point.
