Thread pitch Isco Video Attachment (Iscorama 54)?

Hi all, simple question, can't seem to find a good answer so I thought I'd just ask the knowledgeable crowd here.

So I found an Isco Video Attachment (same design as Iscorama 54, just different stretch factor).

Besides being heavy, MFD is 2m which also impacts practical shooting. I have some 82mm and 86mm diopters to use so I would like to buy a step ring.

Front filter size is 95mm. Thread pitch is larger than normal though...Does anyone know it's specifications and/or have suggestions for suitable step rings? Thanks a lot!

Thanks @tferradans. On the version: I have one without numerical, so just "Isco Video Attachment". I read somewhere that it's actually 1.42x, but to my eyes stretching by 1.33x looks better. Have to do some formal testing though.

So by regular 95mm you mean 0.75mm thread pitch?
I think i can see that the thread pitch on mine is wider/deeper (probably 1mm).
Perhaps I'll just take my chances on a cheap chinese step ring, they go for a few euros on ebay.
