These vintage leggings were made in the 1920s, and are marked the Improved Standard Drawer Legging style 912, size 6. They are made of brown goatskin, with a side zipper. The zipper is an early production Hookless, produced before the patent numbers on the reverse, which, along with period advertisements for this style, would place the date of manufacture around 1924-1925. The separable bottomed zipper wasn’t invented at this point and wasn’t put into production by Hookless/Talon until early 1930. By that point, the strictly Hookless branded sliders, as found on these, had been phased out, replaced by Talon branded ones of the same shape. These leggings, of course, have the non-separable attached end, located at the calf. These are marked a size 6 and measure 4″ (8″ doubled) at the ankle, 6″ (12″ doubled) at the thigh, and 14-1/2″ long.
