The jack pictured appears to match the A-17080-B2 model shown in the Judging Standards.
“In January 1930, Jack A-17080-B2 manufactured by auto specialty was introduced. It was 8-1/2” high and was the first screw type jack. This jack had a one piece cast steel base and screw housing with no rivets. A new handle for this Jack (A-17081 – B) was required. It was made of 3/8” inch steel rod and was 39 inches long when extended and approximately 19-3/4” when folded.
