SINCLAIR REFINING CO. INC.

The original livery, with differing forms of the S between sources, was replaced around 1960.

The brontosaurus Dino was adopted in 1930 to evoke the geological origins of the company’s products; the version inside a pentagon was registered in 1959. Ocean Ships calls the funnel marking a panel, but a monochrome photograph of Sinclair Venezuela supports the rendered band. Rosanoski rejects Jordan’s apparent attribution of this design to 1939 because the pentagon logo was not adopted until 1959.

This was an alternative funnel used around the change of livery in 1960.
