Vintage Wood Gear pattern for an industrial gear. Has 31 teeth, 12” outside diameter, middle hub OD is 5 3/8” & small hub is 2 3/4”OD. Overall width is 5 1/4”. Stamped 251. The relatively thin walls for its size gives it a nice balanced size and you can see the many small pieces that were fit together very intricately to produce this pattern. 1 tooth has a opening at its base by the hub and the adjoining tooth has a small piece missing at the top corner. (see pictures). The wear corresponds to its age and use. It displays very nicely and adds a decorative industrial touch to your decor. Feel free to ask any questions. Thanks for looking.
