She's home. I "bargained" to $80, and she came home with me.
I looked at the machine "in the dark". Her front hallway light had burned out this morning. I made sure that there was a shuttle and a bobbin. There's a needle too, but I need to find out what type it takes.
At first the needle went up and down a little, but then stopped. The handwheel turned reluctantly, but turned. Then I found the little metal piece that engaged the "clutch" and the needle went up and down. Whew! She needs a heck of a good cleaning, and possibly a date with a hairdryer to loosen some of the old oil up to get it moving.
Here's her "just got home, hasn't been cleaned up" photo:
I also found out there may be a chance that there's a treadle base that goes with this.
Here's the story. Her mom used it til she got an electric machine. She has a treadle base in the garage, she's not sure what it goes to, but it doesn't have a machine in it. I sent her an email when I got home and spotted the 2 drilled holes hidden in the wooden base.
