I have three different types of 66 bobbins; the oldest I've seen was in the accessory drawer of a treadle, back clamp model 66. It looked like they were made on a lathe machine from one piece metal, with only the tiny pin hole for the winder. My other Singers are 1930s to 50s, and they are made for more than once piece, very finely moulded and polished. The new ones I have bought brand new have holes in the side (I guess it's easier to keep an eye on how much thread is left), very shiny, polished, made of one piece of metal. I wish they could polish the new ones equally well in side the "hub" too, the metal is more crudely finished there and not always go on the bobbin winder. I have noticed differences when I looke at pictures of new ones, so they are not all exactly the same.
