I used this lens a while back but on the DX format. Sold it before getting an FX camera. I used it mainly with a WP and a diopter to allow closer focusing.
From some old (> 10 years old) Seacam data: Harald (from price list) has the 18D and SD used with no PVL whereas Stephen Frink (from his website) shows a PVL25. This may have been before the PVL20 came out. Reading this info off my old computer (not the one being used right now).
ps. I had this lens at the same time that I had the RS 18mm lens. Looking at both at both ends (front and back) they appeared identical to me. I was not happy about this (the RS lens) as I was expecting a relatively compact water contact optic rather than what I got, which was a dedicated 8" hemispherical port and topside lens. It was OK on film.
I used it for this shot:
