[GreenKeys] M15 typebars...

[drlegendre .]

Hey wow.. with that patent documentation, and a decent mill.. you could
make a small fortune** selling those jigs.

(** If you started with a large one)

Seriously though, that's a cool tool. Hopefully I won't find myself needing
one, once my Mdl. 15 finally (...) finds its way home. Only 4 months!! Woot!
