It has no springs, just 6 screws, 3 push, three pull, once set and locked, no droop or shift of the optical axis.

Thanks Joe - I wasn't aware of that design.
I've never seen it before.
Do you have to undo one screw at the same time
as you do up the other screw in matching pairs?
If my modification doesn't work well I may
design a new mirror cell with that method.
cheers
