Toc 1890s 1900s 1910s 1920s Prewar Skip tooth Sprocket Bicycle Crank

Early Turn of the Century bicycle crank, not sure of year. All one piece except where the chain ring bolts to the crank spider. Unique design for the age, hardly ever see these come up for sale any more. Nice straight crank with nice threads all around, still has some original nickel plating
