Triggered by a topic on another forum, I wondered what shutters (and lenses) would fit in the GVII recessed lens board?

I have two. One is a factory 90mm Raptor in a wollensak shutter (military). Have no idea what 'size' it may be.

The other is a 75mm SA in a Copal 0 sized shutter. The Copal 0 is a tight fir, but works fine.

Are all the number zero shutters the same size on the outside?

Does anyone know of other shutters (and lenses) that will fit the recessed lens board?

I've seen the question of wide lenses for the GVII come up before, but I've never seen a list of lenses that could be used...

I wonder if the issue is how hard the shutter is to adjust?
