Edelrid Cupid Steel Dimensions?

Anyone have an Edelrid Cupid Steel they can measure? I’d like to know how thick the steel actually is. More specifically, how small (ID) of a ring would fit on it?

Thanks!

Edelrid says the steel Cupid has a 70mm diameter and Hownot2 says it has a 44mm ID. Why does Edelrid not list internal diameter? Why does HN2 not list external diameter? Beats me.

Regardless, so long as you trust the accuracy of those numbers, that tells you that the bar stock the ring is made of is about 13mm thick. 

Thanks Slim!
