BENSPORT - 14" DIA. BRAKE DRUMS.
On looking into this matter in connection with other parts of the brake system we came to the conclusion that some modification to the existing brake gear - other than mere scaling up - would be needed, and therefore we decided to make the two drawings - S. Schs. 3970/71. - herewith (Front and Rear Brake Shoes)
It will be seen that we have slightly varied the proportions compared with the standard scheme.
