I have one like that complete with white cord. This Kenmore looks like a Hoover 150. I found mine at a swap meet for $25.00 and I thought that was a deal for how old the machine was and how rare as you don't see these often in Southern California. I intended to change out the cord until I noticed it was a genuine Kenmore replacement cord. I thought if the ownwer thought enough to take that old of a vacuum back to Sears to have the cord replaced, I would keep the cord as is.
BTW, that vacuum may have six wheels underneath it. Mine does.
I hope you get it.
