This style was used for the 28-9 gas cap. The difference between it and the radiator cap is that this one is vented. Chrome with gasket.
The 1928-29 gas cap gasket is made of cork, and the 1930-31 is made of treated leather.
When filling the gas tank, lay this down on the top of the tank to protect your nice shiny paint.
