Apparently these three lenses share either an identical or almost identical prescription. However, I haven't been able to find what that prescription is, can anyone help?
The VM says the Wray Playstigmat covers 60 degrees wide open and 90 degrees at f32.
Has anyone used one of these three, how do they compare to a more modern wide angle?

The Orthostigmat isn't particularly wide angle. The Collinear is wider.
