Can you post a picture of what you can see?
Can't post photos here,
Tony and I assembled a page of photos, which can be
found here:

Opine away!
although time consuming, and requiring som moderate machining skill, that
looks like it shouldn't be an extreme problem to make a blank.
I assume that Tony has, or has access to, a precision milling machine.
It also looks as though it could even be bent out of flat stock with a
miniature bending brake.
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)
