willn Report post Posted January 4, 2020 Hello, guys (and gals). I was hoping someone could chime in on info on a Singer 552 series chainstitcher (not for leather). I really can't seem to find any info on these, and parts seem non-existent. Are they related at all to the venerable 300W? I've got a line one one for $50, but the dearth of information is putting me off....The particular one is a Singer 552x37, and appears to be 1 needle, 2 thread. Thanks!
