In October 1928 the A-17080-A jack, made by Walker and by Ajax, was introduced. It was similar in design to the earlier type, except it did not have the top extension. The Walker and Ajax versions were nearly identical except for the shape of the bases. The Ajax jack had square corners on the base, while the Walker was rounded. Both jacks were 9 ½” high and used a new handle (A-17081-A) made of ¼” x 7/8” flat steel, 20” long with a quarter twist 3-7/8” from the handle end and a tire tool on the opposite end. This jack was used thru November 1929.
