Daniel, the answer to your question regarding the Superor tag on the table is...yes and no. The three-way or side-servicing table had a long and complicated history. Side servicing was invented by Wilbur Myers and introduced in 1926 on Eureka products. Three-way servicing was conceived by Bill Heise, patented and placed into production by Henney in late 1927. Eureka later revised its mechanism to offer three-way servicing. Henney sold three-way mechanisms and tables to A. J. Miller and Cunningham while Eureka sold them to Flxible, Meteor, and S&S. This eventually led to a protracted and rather nasty law suit with Henney sueing Eureka and its customers. In the meantime Henney and Heise continued development on these tables and Earl Schofield - who worked for Henney - developed a power assisted three-way table which Henney patented and placed into production. The law suit was eventually settled in Henney's favor but, an agreement had been reached between Henney and Eureka. From then on, Eureka contiinued to supply tables and mechanisms to Superior, S&S and Meteor while Henney sold these to Flxible, Miller and Cunningham. When Henney went out of business in 1954, and after halting the production of three-way tables, most manufacturers sourced these from Eureka but, the original patents awarded to Myers, Heise and Schofield still applied. When Eureka went out of business in 1964, Superior purchased the defunct firm's parts inventories and the rights to the tables and continued producing them - making significant improvements over the years. As I said, it's a long and complicated story but, the tag on your table does have historical significance - but perhaps only to us professonal car enthusiasts. The full history of this table and the complications and legal aspects of the invention can be found in McPherson's Eureka and Henney books.
