    This is a Shay with a Bux? engine. The HT lead was corroded and fell off leaving just this stub of stiff wire sticking out from the coil.
    Has anyone come across this type before?
    My question is, does the lead screw onto this stub in the same way some plug caps do or would it be soldered to the stub?

    Charlie , I’m fairly certain it’s soldered directly to the coil.

    Thanks Andy, that is what I was thinking.

    From memory there were two different ignition units on the 120 , Miller and Lucas.

    Andy, I would say it is a Miller as it looks nothing like a Villiers. The points are mounted on a brass plate and operated by a cut out in the crankshaft.
