I'd love to see a picture of your Sewmor 110 machine. Last Saturday I got a Sewmor 202 for $15.00 and she needed a new foot control and wiring. Mine is shiny black, like the Singer 15's and has the tension control on the faceplate of the machine. Her lettering and decals are all in gold, and she came in a brown leather-like case. Because the wiring just before her foot control was bare and twisted together, when she was plugged in, she ran like she was going 100 mph. Before I tried plugging her in, I did try threading her up and sewing with her using the hand wheel. Whoa Nellie sews a perfect stitch. Unfortunately I can't post pictures, or I'd post one of her.
I downloaded a generic instructions for the Singer 15 clones for my machine. Good luck with your new machine. Does she look anything like the description of mine?
