Hi,
How are the balance cock jewels removed on the 3/0 size 4th model Illinois? There are no screws that hold the settings in from either the top or bottom of the cock. Is this a friction fit where they have to be pushed out?

Mike,
these are friction set jewels.They push in from the inside.They push out from the outside.For the bridge,select a flat face staking punch that will go in the hole and seat on the jewel setting.Not the jewel itself.place the bridge on a piece of pithwood,press with the punch and see if they don't come out together.
I might not explain this correctly so ask any questions you have

Thanks Julian, I had never seen this before since I usually work on pocketwatches.
