CME or Central Mining Equipment Company was founded in St. Louis, Missouri in 1928. Their first product line included augers, cutters, and mini accessories. In 1962 they produced their first drill rig. Around the early 90s, they launched a very small line of mini excavators the M12 and the M15. Their main focus, however, has been on drill rigs and mining equipment. Today they design and manufacture drilling equipment for the geotechnical, environmental, mineral exploration, and construction industries. They also produce support equipment and all-terrain carriers. It seems that they are producing or planning to produce any other models of mini excavators in the future. If you happen to own either an M12 or an M15 you own a piece of history.
