Can someone with the RT90 / AS90 / Innorel / Artcise tripod do me a solid?

Anyone with the RT90 imported tripod or its sister under a different Artcise brand, specifically the 75mm bowl flavor. Could you grab me this measurement please? Curios if this is 75mm, or the bowl adapter, or the hole it sits in, in the tripod.

Scalped image off Amazon...

Much appreciated.

Here is another one so you can see variation.

So they're basically a red one short of 75mm. Thanks again for the pics. Appreciate it.
