Are chatons different?

One of the endstones is clearly thicker and that’s for the balance cock but I don’t know whether the chatons are also different. One chaton jewel is darker than the other, I swapped them round to see whether it is the light causing it but it doesn't appear so.
The assembled incablocs, the chatons are in the same place, I swapped the endstones.
It looks to me there is no difference but I don’t know for sure.

I guess different in distance between the jewel's and chaton hole, The jewels in them could be different too, as for their hole diameter, thickness etc. 

The movement can run even though one may not belong.

Yes they very often are different hence never mix them up. I have a KEF ref book and it shows clearly different heights for the lower & upper chatons.

Many are different, that is why when you take them apart it is vital you keep the parts separate. If not you are going to create problems for yourself.

Now I know! Thank you guys.

Keeping them separate is definitely the safest way to handle it and most likely what I’m going to do in future.

Alternatively I could measure them with a micrometer during disassembly and take a note but if only the diameter of the pivot hole is different I don’t know what I’d measure it with, I doubt calipers would cut it.
