Hello,
I'm new to the quilting board. Recently the bobbin thread winder on my Singer 1425N quit working, I suspect because the part is plastic. I have been unable to find a sewing machine repairman locally, but when I saw a portable, vintage Majestic sewing machine at a local second hand shop for $15.00, I immediately bought it. It is extremely heavy, due to the all metal parts I believe. Anyway, it had just two bobbins, but I would like to purchase more bobbins. These have no indication of size on them.
