I have just bought a Nikkor W 360mm f6.5 in Copal 3 shutter which came mounted to a thick wooden Deardorf board.
I think the lens will just about fit on a Linhof board but i need to make a Copal 3 spacer ring to make up the difference between the old wooden board and the modern cast aluminium Shen Hao boards as the ring was missing.
I do have a spacer ring on my Apo-Symmar 240mm which i could measure but, so i don't have to strip it down, wondered if anyone had the correct dimensions of these rings so i can make one up on my lathe.
It is not the shims i am looking for, just the spacer which goes under the threaded assembly ring as shown on this ebay listing
