Hi,
If you mean the small plates next to the points, no they are the base units for the Knightwing point hand levers.
They have slowly fallen off over the past few years during tracking cleaning and I’ve not got round to replacing them.
It’s on the list of jobs to draw up some replacements for etching. Should be a bit more robust.
We use Tortoise motors on all the layouts we exhibit as we can’t find anything better.
Thanks for finding that video, not seen that before.
Thanks
