I found a picture of the Singer I used to have.
And good news, is that I found a thread guide for the SewMor. I'm not sure yet if it's for the exact model that I have but I think it will give me a good guideline to go by!
The link for that is here. I can't wait now to see if I can't get this one running. Maybe I won't need to buy a new one if this one works.
