CLB 75 tank

The CLB 75 Tank was a U.S.-produced, prototype armoured fighting vehicle built by C. L. Best's Traction Company of San Leandro, California. Best was a rival of the Holt Manufacturing Company in producing caterpillar tracked vehicles. Among Best's products was the CLB 75 hp 'Tracklayer' The tank was developed by putting an armoured hull over a CLB 75 sometime between late 1916 and early 1917.

The tank was widely photographed on July 4, 1917 parade in San Francisco. Only a few models were used one of which had a semi-cylindrical hull with a turret and another was similar but the hull had flat surfaces. The tanks trained with the California National Guard.
