That's a blackside Singer 128. It is a 3/4 size machine, but not a light machine. Mine weighs in at 29 pounds. I paid $35 late last year, but I didn't get a book or attachments. That is a good price for a complete machine. The blacksides are apparently desirable, which I did not know when I purchased it. I like the lines on my little cutie and, yes, she sews a nice seam. Mine also is from 1952.
