Another question, as tiltle really.

I have a 90mm f8 Super Angulon and a 47mm f5.6 Super Angulon XL, both in Copal shutters and both seem to require mounting in recessed lens panels (might just be able to get away with the 90mm in a flat lens panel) to enable infinity focussing on my Toyo C monorail. As the Toyo recessed panels are 40-45mm deep, it is not easy to get to or even see the lens controls well.

Is there a recognised way to mount the lenses within the lens panel?
