No hair splitting! These are the essential parameters that seperate the men from the insane. I'm clearly on the insane side: when you wrote that they existed, they needed to be found. So....
Found a NOS lens, original" Sidler " branded and it comes indeed with 2 rubber rings!
Flat style 3mm thick, 8 mm outer, 3.8 mm inner, (4 mm will work just fine).
Screws are stainless M4x12 with a Philip's (2?) Sized head.
Even more cool is the little paper bag with info in 3 languages. As if you would not know what they were when you got them out of the bag.
I just love how these things just find the light, after spending some 40 odd years or so on a shelf somewhere....
