If you had come across that machine personally, I hope you can pick it up, that way all the wrong parts can be taken off and given to those VacuumLanders who want those parts for their machines by color.
Or. . . you can add some pseudo attaching lug (whether of wood or epoxy) to the back of the Sani nozzle casting to make it work with the Classic Omega/III/Tradition speed switch. Just be sure to place that pseudo lug where it will meet with the speed switch arm.
