Extremely accurate reproduction of the early 60's Filtertron bobbins. Made from semi-translucent nylon, just like the originals!

Excellent product. They look exactly right. Once tapped properly to 6-40, they are flawless.
Ordered these bobbins which seem nicely made and vintage accurate, but the matching Fillister pole screws with 6-40 threading don't screw into bobbins without extreme force. I think these maybe in fact threaded for different screws.
