Yeah, I was digging around their website and I don't think they do. Who is GGG, sorry, I don't recognize a name associated with those initials. I'd love to get it done if I can, but will survive if I have to let it go past the new year.
Also, does anyone have a Digikey part that would fit the switch location on the loco? I don't have anything similar in my box of old parts with the right screw hole placement, and I'd rather not guess.
