which is the filter diameter for 120mm Schneider lens TS for

[NN634457431486789123UL]

The manual mentions the bayonet VIII - 104mm diameter, but looking at B & H, I find these measures, only bayonet 6 - diameter 105, to measure the diameter of my lens between 94mm and 95mm gives me. I can say the exact size of the filter in screw, no bayonet.

Thanks

Was there ever an answer to this question?

I have a Schneider 55mm PCS lens (tilt and shift) in a Mamiya/Phase One mount, it too requires a Bayonet VIII/104mm filter which I'm struggling to source. Plenty of 105mm filters out there, would they fit?
