This thread is three years old, but for anyone else googling, the pump is a Southwest ETA style pump made for the Gulf Oil Company, thus it should have either a Gulf Oil tag on the side or a Southwest tag with GOC in the number. It was never made by Tokheim, I'm pretty sure that was an auction buzzword. Regarding the ability to price gas to $1 a gallon, I wouldn't read anything into the mechanical computer vs. the date on the side. The computers swap out with 3 bolts, and either the person restoring it could have changed it, or the person that sold it.
