Up for auction is a vintage PERFECTION fiber timing gear. This gear was made by the Perfection Gear Co in Chicago. The stock number is 624. I am unsure of what vehicle this was for so. Gear is 5 3/4 across and just under an inch thick. There is 50 teeth. Gear has never been used. The box is old and worn. Please see photos. If you have any questions or need more photos please ask. Thanks for looking.
