  The Cherenkov Telescope Array (CTA), is an international project for the next
generation ground- based observatory for gamma-ray astronomy in the energy
range from 20 GeV to 300 TeV. The sensitivity in the core energy range will be
dominated by up to 40 Medium-Sized Telescopes (MSTs). The MSTs, of
Davies-Cotton type with a 12 m diameter reflector are currently in the
prototype phase. A full-size mechanical telescope structure has been assembled
in Berlin. The telescope is partially equipped with different mirror
prototypes, which are currently being tested and evaluated for performances
characteristics. A report concentrating on the details of the tele- scope
structure, the drive assemblies and the optics of the MST prototype will be
given.
