Hi all, posting this very long shot request in the hope that maybe someone has one of these lying around they don't need. This is essentially a step up ring to fit a 67m wet lens like the Inon UWL 100 onto the 52m port of the Recsea housing for the RX100 IV/VA. Here is a photo from Backscatter (they don't have any and it's been discontinued). Importantly, as you can perhaps see, this is a female to female, plus an added recess to accommodate the little bulge the wet lens has. I've tried numerous other step up rings and either they don't fit, they aren't female to female, or they are too flat to accommodate the wet lens, or all of the above.
I'll pay $100 PLUS shipping for even one of these! Many thanks.
