The Buch Concern was founded by Scharnhorst Buch in U.C. 0055. Scharnhorst eventually bought and changed his surname to Ronah. The company has many subdivisions including Buch Junk Inc., and the mobile suit manufacturer, Buch Aerodynamics. By U.C. 0121, it was well known that Buch Aerodynamics built and sold a civilian use mobile suit known as the Dessa Type.
Later, Buch Aerodynamics provided the Crossbone Vanguard a series of advanced military mobile suits that surpassed Earth Federation MS manufacturer Strategic Naval Research Institute's own F-series of mobile suits. These mobile suits were equipped with the beam shield, a powerful defensive technology, which was yet to be implemented by either SNRI or Anaheim Electronics, the two main constructors of military mobile suits of the time, on mass production units at a large scale. The Crossbone Vanguard itself has its roots in a vocational training school set up by the Buch Concern.
The Buch Concern fell on hard times after the fall of Cosmo Babylonia. They did provide some support to the pirate group Crossbone Vanguard led by Berah Ronah, however the endeavor was not profitable and they ceased producing the parts needed to repair the Zondo Gei mobile suits they used. After ending their support for their older units, the Buch Concern fell into obscurity in the field of mobile suits, with their position as a supporter of the pirate Crossbone Vanguard being taken up by SNRI, who would continue the "XM" line of mobile suits with the XM-10 Flint.
