Henry,
You can also find on the Singer website what model your machine is and perhaps even download a free manual for it. I was able to find the free manual for my treadle machine which is a model 127 made in 1928. I have several feet and attachments that came with mine.
My DH keeps all my machines shined up with Simonize Paste Car Wax. He even uses it on some of the cabinets, they really shine and the fabric slides so easily when sewing.
Enjoy your new toy...
