This is a new replacement power cord for many older Singer sewing machines, including the 401, 401A, 403, 404, most 301's, 15-91's, and others.
Please look at both photos to see a close-up of the molded rubber plug that fits into the machine. If you have any questions about which cord is the correct one for your machine, please contact me before ordering.
I test each cord before I ship it to ensure that it fits and works well.
I am happy to combine shipping with other items, and also to help to to find other items for your sewing machine restoration - please let me know how I can help you.
