I believe is from the 1920’s – 30’s. IT HAS A LEVER ON THE LOWER SIDE AND AN ADJUSTIBLE KNOB THAT ALLOWS FOR TILTING THE FAN. THE PLATE READS WESTINGHOUSE, 60 CYCLES, 100-120 VOLTS, STYLE #363329. WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, NEWARK, NJ USA. MEASURES APPROX 14″ HIGH AND BLADES AE 4 1/2″ LONG. BESIDES NEEDING TO BE CLEANED UP, OILED AND PAINTED THIS IS IN GOOD SHAPE FOR THE AGE! THIS IS VERY HEAVY AND I THINK IT’S A CAST IRON FRAME AND MOTOR HOUSING.
