The Forest Automobile & Forest Motor Car Co.

The Rayfield Carburetor was made by Beneke & Kropf Manufacturing Co. Of Chicago, IL. Their magazine advertising had the following to say... Rayfield Carburetor's have proved repeatedly that they give a wide range of performance with greater economy.  This is why they have been adopted as standard equipment on so many of American's best motor cars.  Made with absolute precision, Rayfield Carburetors can be adjusted to meet the most exacting requirements of any motor.  Once adjusted they ordinarily require no further attention.  Our engineers are ready to co-operate with yours in making test on the motor.  Manufacturers have found that the added owner satisfaction in car performance more than justifies the slightly higher cost of the Rayfield.
