 John B asked:
>>Are all apertures on the same centers?  What centers are >>they on?  62.5
mm?

Good point John....and in the instructions that I give to people, I mention
that the European mounting gauges offfered by Reel 3-D should be used for all
RBT apertures.  The center spacing on the RBT's are around 78.5mm as I held a
ruler to it at 
2:40am.....time to get some sleep. 
Anyone out ther want to try one free sample....just email me and you can try
one of the following sizes. Goodnight, ZZZZ JON GOLDEN RBT USA  
 Five sizes available: Non-glass, and One-sided Anti-Newton glass
 RBT 4  Nimslo format   21 x 16mm 
 RBT 4G Nimslo format   21 x 16mm with Anti-Newton glass
 RBT 5  Realist format   23 x 21mm
 RBT 5G Realist format   23 x 21mm with Anti-Newton glass
 RBT 7  Euro format      23 x 28mm
 RBT 7G Euro format   23 x 28mm with Anti-Newton glass
 RBT W Wide format   23 x 31.5mm
 RBT WG Wide format   23 x 31.5mm with Anti-Newton glass
 RBT F  Full SLR format   23 x 33mm
 RBT FG Full SLR format   23 x33mm with Anti-Newton glass
         
 One-sided glass mounts  helps if you project, especially in  7,  W & Full
formats.  Two anti-Newton glass pieces nest flush into left and right
apertures of a white halve, providing one-sided protection from bulb heat,
eliminating popping of the emulsion for more accurate focusing on screen.
