Looking forward to 10 OP photos taken with your DSLRs :D

The 10 OP looks almost mint. Good on you.

Uploaded a few in the meantime

It was sold as mint, in fact  there is some very tiny mark on the rear lens that would not reduce joy so I'd call it near mint

So you confirm the 10 OP can indeed be used on a modern camera ... great.

Not easy to ascertain sharpness on these test images, though. If the internal filters are dirty, flare outside the image circle easily arises.

Here is 10 OP on the Nikon Df. The lens is surprisingly sharp.

The advantage with this approach is of course you can, and ought to, use LiveView for framing. My 10 OP is (surprise, surprise ...)  equipped with a CPU, thus exposures are spot on.
Fine pic
I indeed  use life view. But surprise surprise ;-) the lens is not equipped with a CPU so I am adjusting the lens settings manually.
My chipping project still  due and will start with other lenses first

so far it works on FX bodies, with DX it is very narrow so if it works it needs a lot of care

Images are downsized, was not too much light and handheld so sharpness could be improved
havent done a lot with te filter revolver so far

The NG Community simply amasses rare Nikkors. Thus we have at least 2 out of some 700 units of this rarely seen lengend.

Are there more of these lenses found within the NG audience?

True
also true for the Voigtländer 125 mm Apo Macro Lanthar, but that poll probably should be reserved for another thread

For DX I initially used a relay system to shrink the image circle to fit inside the smaller DX frame. This had the added advantage of providing a (narrow) range of focusing the lens. The 10 OP is natively a fix-focus design.

A few examples areas follows;

probably would need to search a few additional K and BR rings to imitate your relay system

and maybe continue search for a
Repro-Nikkor 85 mm f/1.0 as well (58 mm and 35 mm have worked as well according to your description)

You could use the 50/1.2 and 35/1.4 (or f/2).  This combination, in conjunction with a focusing stage, works pretty well as relay for the old fisheyes. Do note only lightweight fisheyes should be used lest the strain on the focusing mounts and filter threads  be excessive.

Getting the elusive (and expensive) Repro-Nikkor 85/1 solely for use as a relay is true overkill. Of course, if you have such a lens floating around, by all means do use it though.

Havent got the 50/1,2 but the 58 mm Noct and both 35 mm lenses. Evident that the strain needs to be limited, so nothing for the really heavy 8 mm. I wondered how lightweight the 10mm OP Fisheye actually is, I had expected it to be a bit bigger and heavier.

If i ever get it it wont be just limited to relay duties, dont worry

Would it be possible to use a a relay lens in combination with a "shaved" Nikkor 10.5/2.8 DX to get a full circular image on an FX camera?

Probably, but available scale factors are limited by the focal ratio of the lenses of the relay module. Around 0.7X (or 1.4X if the module is reversed) is easy.

Combining two images taken with the 10.5mm and camera rotated 90 degrees between them will suffice, and is far easier to implement.

Here is a 10.5 mm capture on Nikon D750 (FX).

Oh, I haven't expected that you have D750.   ::)

Not my camera, probably 'retrieved' it from Jakov on a shoot in Delft, The Netherlands. The 10.5 just 'happened' to be on the camera :D

I have tested the D750 and didn't like it.
