Here are some photos - hope they help. Please let me know if you would like me to dismantle one of them and take some more photos. I don't remember seeing any brass discs in them, and I couldn't see any when I was peering at it just now. The centre bushes were lignum vitae which I think is a sort of wood, although we'd probably use nylon these days.
