Oh well! The search continues...
Somewhere, maybe in this very thread (and maybe not) someone mentioned a civic building of some sort in the UK having public restrooms being loaded with the correct handwheels. I spoke to the member about a year or more ago but they didn’t have the name or location any longer. I would be all for helping fund a group buy of matching NEW AS handwheels IF the place can be located, AND if they still have the old AS handwheels, AND if someone or two UK chaps would be willing to deliver and install them.
Just a consideration I’m throwing out there.
