I picked up a 1960s vintage 6" Mak Cass. I believe it was a kit scope.

It is missing the 1.25" rack and pinion refractor focuser. I've included pictures of the scope with the original focuser to give a feel for what is needed, and a picture of the diagonal / flange the focuser would attach to.
I believe the original focuser that was on the tube was from an older 70mm refractor. The focuser would bolt onto the outside of the pictured diagonal. The measurements of the outside rim is 70mm / 2.75".

Please let me know if you have something I could use.
