Old Style Dillion Puller

[beb1954]

Would anyone be able to tell me the dimensions of the collet o-ring used in this old style puller? Called Dillion and they told me that the new Berry's that they sell now are different and they don't have the o-rings for the old one's any longer.
I've tried using this POS caliper I have but never get the same reading from it.
It seems to be standard as I have a metric kit but nothing comes close and are much too thick.
Thanks....
