Bowser had two "Siamese Rol-Way" pumps. The first was the Model 22 and was introduced in 1951. The other was the Model 22-C and was introduced in 1955. The second one had the "TV Model" face. Both are picture in my Gas Pump Identification book, due out on May 10, 2002. If you are interested, I have for sale, color ads, sales literature and parts/repair manuals for both pumps. You can contact me at: jhsim@swbell.net.
