Describe Best Company here
[ question: what is this about? what era? It needs some basic info, or it should be deleted ]
[potential answer: probably related to Daniel Best, who had a factory in Oakland before moving to San Leandro and eventually co-founding Caterpillar Tractor; see these links:
Also see Harry Heasley Fair, who married into the Albert Miller family
]
[potential answer 2: It is probably the C.L. Best Gas Traction Company. Daniel Best sold the Best Manufacturing Company to Holt in 1908. But in 1910 his son Clarence Leo Best started the C.L. Best Gas Traction Company to manufacture wheel-based tractors. In 1912 he started making track-style tractors and by WWI took the technological lead. Holt and Best family-owned companies again merged in 1925 to form Caterpillar, using C.L. Best's technology and the Caterpillar branding from Holt.
