]Ok guys I bought a box full of old watchmaker tools and supplies and these two items I can’t figure out what they are. Can you?



These are little aluminum (I think) cups that are two pieces that slide into each other. there are 7 total from large to small. They are all quite small with the largest the size of a thimble.

This picture is a pulley that is very small and I have about 8 of them all small and different sizes. What do these go to?
