Hi,

I'm trying to determine the part number and potential source for the 15th Position Switch stack in the bonus stepper for Target Alpha. It has an alternating switch and a normally closed switch.

First picture is off the internet from a typical one. Second picture is mine; it has been previously, ingeniously repaired (nicely! and works fine) but I may want to replace it someday. Third picture is from the parts manual, and the part I think it is, although maybe upside down.

Can someone please confirm if this the correct switch stack part number, or it's actually a different part number than the one I've shown.
Also, is it still available from someplace, or you need to build the stack yourself from separate switches.
I've looked on pbr and marco and don't see it. If I told Steve at pbr what I'm looking for, would he have it or be able to build it?

Thanks!
