Hello Jeannie,
If you just need the foot control without the lead most controls will do unless you need an electronic foot control, you can use the machine with a standard control, if you need the control and lead you need to go to a Singer dealer otherwise any good sewing machine shop will supply them, you have not said why you need a new foot control, is it missing or is there a problem with the one you have? you can get them on line if you are in the US, www.tandtrepair.com or if you are in the UK www.sewingonline.co.uk/instructions, e-mail me for any help.
