Here's a great gear assembly made by Hankscraft. Has 5 wormhole gears and (6) 5/8" gears that work in succession to move the hook 360 degrees. Measures 2-1/2" long and has a mounting flange that extends to 2 5/16" with two 3/16" holes. Unused. This may have been used on a motorized tie rack (that's our best guess!).
