Lanshire Double Stack Clock Gears
There are actually two gears here. The top one has a shaft that goes through the bottom one. We sell them as a pair. If you order this you will get both of them just as shown. The number 6008-1 is commonly molded into the bottom gear and 6012-PS is sometimes molded into the top gear. The top gear has the jagged teeth that mesh with the anti-reverse gear that keeps the movement from running backwards.
