Sectioned automobile carburettor, metal, maker unknown, United States of America, 1926-1936
Automobile carburettor made of metal, cut to show the mechanical operations. These include the choke and throttle valves in the barrel through which the air supply passes and the float valve devices in the barrel through which the gas supply passes. The exterior of the carburettor is dark bronze, brown and silver in colour.
On one side of the carburettor is 'S(illeg.)' stamped and on the other side is '(illeg.)BL / (illeg.)PO...(illeg.) / (illeg.)...A' stamped. These marks are illegible in the sections where the metal has been cut away to show the internal mechanisms. 'MORE - LESS - GAS' is also inscribed in a circular motion on the other side and this appears again 'MORE - LESS - IDLE GAS' with two arrows indicating the turning direction. '8V 18' is also stamped horizontally in one section.
