Old 12 inch brass fan blade. Has a 3/8" id bore size, set-screw turns as it should. I held a magnet to it and the only thing it attracted was the set screw. Seems to be pretty straight. Sold as pictured. Payment due within ten days of auction end via Pay-Pal, check, or money order. All items are carefully packaged for a safe trip and usually ship within 2 days. Please direct any questions/comments thru ebay using "ask seller a question". Thanks for looking and good luck!
