Old Dad Watson Secret Lure Spinner #5. Very hard to find this spinner, especially in such good condition.  About 6 1/2" long from hook to line tie. This antique spinner is used with some minor wear but is overall in great condition. It's feathered treble hook is even in good condition. See photos. 

This bait is inscribed with its #5 size and the year the design was patented (1934)
