Another thing with White VS- the shuttles often cost $20 on eBay, though they aren't that hard to find. The shuttle has a pin in the middle and the bobbins are hollow.
I remember the first time I came across a White shuttle (before I knew what it was). I thought a bobbin had gotten stock and the end pulled out. I tried to remove that pin but it wouldn't budge. Figured the shuttle was not usable so tossed it.
Boy did I feel stupid when I got my first White and realized I'd tossed one of the more expensive shuttles!
