Sounds like fun. I still have the first machine I bought when I started working - a Singer 503 Slantomatic. What a great machine, even though I don't use it any more. It has cams that snapped into the top for zig zag and other decorative stitches. It was top of the line at the time. The nice thing about these old Singers, is that you can grease and oil them yourselves. They rarely need service.
