ok- I think I got more than I barginned for.
DH got home very late, so I peaked in the van to see what he brought home. He told me there is at least another full load to pick up . . .
It turns out the seller had way more than what was pictures, and since she and her husband took a liking to my husband and his machine enthusiasm, and like what we are going to do - they started pulling out stuff they had stashed here and there. I expected to get three older whites and two 127 Singers, and Dh said there is more machines than that in the van - including one industrial.
The seller is into woodworking and collected treadles over the years, restored some and decided it wasn't worth the effort as there is basically no market, and now her interest has changed and her husband wants the room in his shop - DH said there are a lot of dismantled treadle bases, as the tops were not salvageable (there are also lots of drawers) so we may see if we can make some "universal" type treadles just like how we converted the parlor cabinet.
DH is going to clean a spot in the Boat shed (boat was sold this spring) and we'll unpack tonight - I'm excited to see what I've gotten in the first load!
This fall we'll build our "Machine Museum" and then these will have a more permanent home.
