There is a strong link between 'Mountain' and 'Takamine' ( which is named after a mountain !!! ) Coast Wholesale Music of San Francisco, wanted Martin to do a "Cheap" line of imported guitars, and Martin approached Takamine to make them.However,Martin pulled out when Kaman took over Coast Wholesale.Martin then concentrated on their cheap " Sigma" brand,while Kaman helped to finance Takamine to the extent that Takamine gave them the rights to distribute their guitars in the US. Many of these early guitars were direct copies of Martin dreadnoughts & OM sizes, and carried logos that looked VERY similar to the Martin logo !! I can"t find any direct references to Mountain guitars, but I would not be at all surprised to discover a link with Takamine, given that company"s early history.
