It is a Kenmore 158.1654. I just got one free from a woman at church moving into a nursing home. I bought a new belt from Sew-Classic, 20 cams for $10 on eBay, and am putting it in a case out of the cabinet. It is a sturdy workhorse. You have to see if it runs. If it runs, it is a solid machine. You can find the manual online for free.
