I'm assembling a Royal Astro mount for a 76mm (the "clock face" one), looks like I'm missing the plate with latitude angle and the thru bolt and handle? Could be missing the finder scope but I'm hopeful of having one here so I'm searching but what have you got hidden in your shed?....
Finder is lost so I've borrowed a finder from my little 100mm Royal Astro reflector and it fits so if you have one of those anywhere ,plus one adjuster screw needed
