I found these today in a box in my shed marked old Marx switches.
Any help dating these and part numbers would be of great help. I doubt they are worth much but just don’t know. Seems to be three different styles of remote and a set of manual.
I tested these today. All but one of them slapped open and shut and I found a track screw lodged in the one that was slow but it is fine now. The controllers work too.
LL675, give me a PM if your interested in a pair. Will see if I can help you out.
