The only evidence we have of this lift is the ad that appears in the eWillys article below. Bob Westerman sent us this same ad. Although the eWillys article indicates a date of 1954, we thing it might be an earlier vintage. The ad states that it will work with Newgren implements, which were only produced in the late 1940s.
Scheneker Iron Works were most well known for their Jeep snow plows. Note that the ad states that the same hydraulic system can be used with the snow plow setup.
Dave added another post with more Scheneker Iron Works information.
