I have some near new Losmandy DR125mm (5.0") I.D. rings with three point adjustment, Delrin tips. Weight: 2.5 lbs. per set, 2 rings per set, dovetail mounted, no tools needed. I.D. size from 3.1" to 5.0". Will sell them for $120 + Shipping.
Also have near new DM8 Meade dovetail plate for 8" and radius blocks, which bolts to existing holes. Weight: 2 lbs. Length 13.5". Will sell for $75 + Shipping.
Would prefer to sell them both together for $190 + Shipping, and you will save on shipping if they are in the same box.
thanks Nick B
P.S Also have Losmandy Counterweight set + extra weight if interested.
