Hi! Welcome to the board.
The machine is late 50's. I bought one a bit ago at a yard sale. (It will go to my daughter when we visit her.) Sears has a site online. At one point I discovered a chart there for dating the machines, but seem to have misplaced the bookmark, sorry. (Not the best on computers. :roll: ) There are all kinds of attachments available for the machine - the box that was with this machine (box labeled sears - attachments labeled greist) includes a binder, hemming foot, seam guage, edge stitcher, ruffler, and some other things I haven't fully identified. Have fun experimenting! You will love your new machine. And be sure to join the crew in the vintage sewing machine shop. You can learn a lot about older machines there.
