Thank you everyone for looking at him... her?? I can't wait to get started! Good thing I can back the truck up to both front porches to load and unload.
The more I think about it, the more I like the suggestions of returning it to a treadle machine. I think there is a rod or a belt missing from the treadle to the wheel; possibly it was removed when the motor was put on and they ran the wiring through hole? I'll have to look at the manual and see how all that connects. In looking at some of the sites recommended by this group, Davis and Free machines are mentioned or shown, so I have my fingers crossed on finding any spare parts that may be needed. Thank you for identifying the needle for me. The manual has a 'full size' drawing of the recommended needle with the admonition to buy only needles that match the drawing.... something not in the book for my computerized Brother. Off to print the tuts for cleaning the machines and the cabinet, then order some Tri-Flow.
