Neat machine. It looks a lot like one I picked up in a thrift shop for $10. It's an upholstery machine & a Kenmore. The cord also needed to be replaced. I took pictures of it, the cord, etc then went to the hardware stores looking in the electrical dept. wound up getting a new cord at Lowes. It wasn't difficult to put on & it sews beautifully. My machine uses large metal bobbins and came with lots of attachments.
since your's is a Singer I'd start by looking up the serial # on their website
Good luck
