If you look at your bobbin case and compare it closely with mine you will see they are built different. Mine does not have the overhang that yours has where your spider fits underneath. Also the tube on mine is too large to fit either inside or outside the tube on my bobbin race. It's a no go. Hope others with Standards will post here if they have a spider like mine so we can see what years it will fit. This is very interesting. I think these Standards are a really pretty machine and need kept running. I'm going to keep looking for a bobbin and bobbin case for mine. It moves so quietly when running. Who knows......I just may find one. Keep in touch! And thank you.
