Just like today period rider gear and accessories were not listed in the factory parts manuals. H-D published special catalogs for them. These 1:1 top-quality reprints of early Harley-Davidson accessory catalogues are almost indistinguishable from the original editions and highly valuable sources for collectors, restorers and enthusiasts. They show the complete riding gear and all factory accessory parts availalble back in the days, of which most you didn't know they were.
