I have asked the Singer knowledge base to help clarify the situation. I surely don't want to misrepresent this machine. I shall update when I know the answer. Thanks, Sharon for your question.[/quote]
Seems as though I do have an early version of the 15-91. I looked at the shiny parts in a picture and didn't even notice it was a treadle, so thought an 88. My bad.
