I happen to have a Linhof Angulon that I got years ago with my Tech III so I bought one of these almost right away, but even if I hadn't, I would have bought one. Keeping an eye out over the coming months would turn up something workable, I'm sure.
I have an old Linhof Angulon 90 as well. Bought it two or three years ago thinking to mount it on my Crown but have never gotten around to it. Now I will have a use for it.
