This Model 511 Blend-O-Matic gas pump was built by the Wayne Pump Company of Fort Wayne, Indiana, and was recently refurbished and refinished in blue and yellow with Blue Sunoco decals. The dual-sided pump is equipped with a side-mounted blend selector, dual registers, an external fuel-filter housing, a pump nozzle, and a rubber hose. This gas pump is offered at no reserve in Dundee, Illinois.

A blend selector mounted on the side of the pump allowed the user to choose between various fuel grades. The manufacturer placard identifies the pump model and serial number.

The dual multifunction registers indicate the total sale in dollars, gallons delivered, and price per gallon in cents. Four fuel grades are represented, ranging from Economy to Super.

A rubber hose with a silver-tone Buckeye-branded dispensing nozzle is mounted to the side of the pump body alongside a fuel-filter assembly.
