Andres Gomez-Mena owned two Centrales in the southeastern part of Havana Province; these were dubbed Amistad and Gomez-Mena and had been developed from an area that included swamp land below and almost arid terrain above. The solution, according to a 1920 account, was to drain the swamps and irrigate the highlands.
Sugar-plantation Moguls like the 5 were often bought for the Centrales by dealers. In this case, the company was Czarnikow Rionda & Co. See its biography at [], last accessed 16 January 2012.
Central Amistad would be the first Central introduce multiple milling in 1914 and substantially upgrade grinding efficiency. Gomez-Mena sold both of those Centrales in 1920 to Warner Sugar Refining Company of New Jersey for $16,000,000.

Warner Sugar Company, which had bought the Gomez Mena processing mills in 1920, also bought these two oil-fired plantation Moguls as one of its first acts. They were a bit bigger than the 5 that had served the two Centrals for a decade (see Locobase 13740). 6 was later sold to the Central San Antonio, which was renamed after the 1959 Revolucion and 14811
