recently bought a craftsman 24 inch scroll saw on the double pedestal mount. I am trying to find information if the motor mount is complete or is missing a piece since to me it looks like there should be another piece. Also if anyone knows where I can find the manual for it it’s model 103.20770. I’ve looked on vintage machinery and there is only one picture in the photo registry and none in the publication reprints other the it’s half page mention in the general catalogs from the mid to late 1950s
