It will be cool to see a diagram of what those hole patterns are for on the dovetail plates.
I was pleasantly surprised when the mounting holes on one of my unused Losmandy saddle clamps fit perfectly on the bridge on my Takahashi scope rings.? I attached a metal pull handle to a DUP7 to make lifting my TOA130 much easier.? I can remove the handle and use the saddle clamp to hold accessories on the scope.? Very handy.
