I've been amazed by Bonnie Hunter's interest in old sewing machines. I've searched this forum and found a thread about treadles.

This comes from one of my great-aunts. The serial number tells it is from 1924. It is a hand crank, probably the Singer 28 model. The bobbin case looks like a pen (I think it's called a shuttle?) It's full of dirt and spiderwebs, but it must have been oiled to death as the weel still rotates smoothly and all the parts seem to move properly (haven't tried to put a needle and thread it yet, so I don't know if it actually SEWS).
Do you think it is worth the pain and money to have it restaured for use? Do you know if the parts could be found?
Thanks for any advice or comment about your experience in rescuing vintage machines.
