They're 3 - 3.5mm thick (seems to vary, difficult to measure - the 
plflexes...), 70.8mm square. Thickness measured with micrometer, slide size 
measured with a vernier caliper (couldn't be bothered to dig out the large 
micrometer...!)

Seems to be 3.05mm on inside thicker on outside - so tapering the wrong way!
 
<< Also, when single mounts are used as stereo pairs what mounting gauge
 dimensions are used?  In other words is there an infinity spacing standard
 with a set gap between slides (similar to the Reel 3-d mounting gauge for
 twin 35 slides)?  Or is it a free for all? >>

I'd guess it's a free-for-all! Window is 54.4mm, so the sides are 7.5mm 
Overlapping them would give 63.3mm - possible for viewing without mirrors or 
prisms. The infinity separation would depend on the MOFD deemed desirable. 
I've seen various values for this!  

I'd love to have a SaturnSlide for separate mounts - otherwise I'll have to 
take two of everything if I want to project! (Assuming I can find another 
Rolleivision 66 projector!)
