From the 1960's this is a rare Sonor Quick Release Snare Stand, made in West Germany. Has a lever which loosens basket enough to remove drum and make for a quick set up.
This example is in great condition for its age! Chrome is in good shape, original rubber feet and basket grips are present, and also in excellent condition. Height, angle, and basket adjustments all function smoothly. Really cool stand! Grab it while you can. See pictures for more details!
