Thank You, this is great info. Mine is a 39 short. I wanted to restore it as a Texaco, but I do not know if it was ever a Texaco pump. I assume it was probably used for years and well into the 1960s. I want to display it in the garage with my 66 Mustang. I am picking it up next week so I will chime in the serial number when I get it. Thanks for all the info.
