Judy,
You can get a cord set with connector and foot controller from Sew-Classic if your LSMG doesn't have one.
"Most" Kenmore cabinets I've seen, and those I have, have bolt on legs. There is a threaded screw that the leg mounts to at the top corners of the cabinet, then you use wing nuts to secure them. Finding a set of legs shouldn't be too difficult. Or, you can make a set.
Good buy on that Kenmore. They are very nice machines.
