I didn’t see any other choice but to make my own Korry replicas. I made a prototype master out of 1 mm white plastic sheets. I made a silicone molds of master and started casting replicas. I think I had to make about 90 of them…
Interior is divided in two parts for two signal diodes. Outside is painted black and inside silver. Front is made out of 1 mm clear perspex with laser printed legend on self-adhesive semigloss foil.
I made the lower part of korry replica is narrower to fit into panel korry openings.
For the switching part I didn’t have better solution than momentary push button switch. I also didn’t bother with propper tactile switch and latching.
