Mavita,
I've never seen a Singer attachment or accessory that is marked with it's name, such as Ruffler or Hemmer. Greist did mark most of theirs.
To keep your Ruffler running it needs to be oiled regularly. There is actually maintenance instructions in the manual for that.
Singer, Simanco ( Singer Manufacturing Company ) are both names used by Singer for their products. Simanco is the older name followed by Singer.
What the CTPPIT (or is it STRRIT?) is I don't know.
