Vintage 4 Brass Blade & Cage Sprague 16 Electric Fan Oscillating TESTED. Blades measure 16″ across, cage is 17 1/2″. Bottom piece of the cage is supposed to be bent so it doesn’t hit while oscillating. Cord and plug are in good shape. Looks like it was restored and repainted 20 years ago or so. Tested and runs well. But it has a little bit of a noise as the blades have a little bit of play on the mount. Oscillation seems to work as it should.
