I’m looking for some Llagas Creek Pettibone Mulliken (PM) switch stands. Their product number is PMSSK.

I have a few (five) Llagas turnouts that came assembled with these great switch stands. But my other turnouts (four of them) have Tenmile ground throws.
I was hoping to convert these four turnouts with the PM stands, but can’t find them anywhere. And I need this particular brand to match the PM stands I already have. They really look great, especially with switch lanterns:

Does anyone know if the Llagas Creek Pettibone Mulliken switch stands have been discontinued?
I also have a turnout on the mine section of the layout that currently has a Tenmile ground throw. I think it would look great if it had a Harp style switch stand. This style looks like this:

If this helps any, my Llagas Creek track is 1:20.3 scale. I think these operate a little differently then most switch stands. So I would need one that comes with the various linkages to make it operating.
Does anyone know of an operating Harp switch stand for G scale?
