Armin Weller 1989-2007? Luthier Armin Weller.
Armin Weller was considered the no#1 luthier before 1989 in former East Germany. Llike all guitar makers in East Germany at the time he was connected to Musima , nobody being allowed to build guitars privately by the socialistic Regime. At one point Musima made a “Armin Weller” Line honouring their top-luthier with a top of the line model. After 1989 he started his own workshop in Markneukirchen.

Apparently his guitars are dated and signed inside the body/against the Soundboard. He died around 2007. [Source: The Fellowship of Acoustics]
