Thanks for the welcome, Leon. We're nearly neighbors - I live in Overland Park.
Having never owned a vintage Singer or a treadle before, I know I'll be spending quite a bit o' time researching all things restoration... including how to install the belt. I have the old leather belt - found it in one of the drawers. It was broken, but I at least could see how the two ends are attached to close the circle.
LOVE your collection! I know I'll buy other vintage machines over time, although almost every sale posting I saw before buying this one was for the machine head AND table - very few machines being sold just by themselves or in a portable case. I don't have the space to own multiple vintage machines each in their own table!
