Inside is lined with felt, the rings are mounted 9" apart on the plate, hinged, and the clamps are 1/4"-20 thumbscrews. Everything is painted a dark gray finish. Condition is good - some paint has come off near the thumbscrews and dove tail assembly. Asking $45 US inc. shipping. Prefer postal or bank money order. Thanks for looking.
