Hi, I am selling these beautifully made rings and mounting rail that also comes with a camera adapter. The rings are felt lined, about 4.5" (113mm) ID with 3 plastic set screws that nicely holds my 90mm guidescope. Dovetailed fittings attached to the rings fit nicely into the aluminium rail which screws on to the scope OTA ends. Looking for $75 for the LOT + Shipping. Paypal is ok.
thanks Nick B
