Today I looked under the machine to see if there was a foot pedal attached to the side of the machine. BeeBee suggested it & triggered my memory that the Singer 327 came that way, too.
But what I found was just a true lever - no pedal at all! I even unscrewed the back of the box, hoping to find a miracle and fearing I would have to ... do some electrical ... something-or-other.
Then I posted about it on the Yahoo Kenmore group and got a good answer that propelled me to contact a seller on eBay.
And that was the nice guy who explained to me that THERE iS a Plug. No you do not have to do anything to the wires.
I do have a manual for it now- I purchased that from www.sewusa.com. Nice speedy service on that.
So I ordered the new foot pedal from him. And I am the high bidder right now on "HUGE LOT OF VINTAGE SEWING MACHINE ATTACHMENTS". Fortunately, I can compare the pictures in the manual to the pictures on eBay and that's how I know it will fit this machine.
This is lots of fun- everything is inexpensive and easy to find. I have a soft spot for Kenmores- that's what I sewed on for many, many years. They are wonderful heavy-duty workhorses.
