I guess like needles and shuttles, that the bobbin winders were machine specific at the time this machine was made. According to a cropped screenshot of

I may have to check Ace out and see if they have something that is a little thinner and still fits over the wheel.
I started to take off the hardware from the table top. One of the socket pieces that hold the machine to the table has a leather piece under it - the other side didn't. I'm having trouble getting one of the screws out for the receptacle piece for the hinge of the bonnet. I was able to get the screws out for the bonnet lock receptacle but the piece did not come out.
