Larry, the handsome chap in my first post suggests that I design something for his 4x5 Shen Hao.
I'll probably use something around 200mm focal length.
(His bellows draw isn't as long as my Deardorff's).
While I'm at it I'll probably make one for my 4x5 Tachihara too.

Maybe I should make a few extra, just in case...
This could be fun.
