The Kenmore looks like a 148.13101, which was manufactured in Japan by Soryou. It is a low shank, class 15 bobbin zig-zag machine. It does stretch stitches, has drop feed dogs, and sews through denim layers like butter. It is a lightweight machine and could be mounted into a Kenmore cabinet. I hope you got the buttonhole attachment, etc. with. If you didn't get a manual with it, you'll probably be able to find a pdf manual online. These metal Kenmore machines are easy to maintain. Congratulations on your score!
