Formerly Delta-Gnom, Johann Teichert built quality motorcycles using JAP engines, Burman gearboxes, Bosch electric and Amal carburetors. Frames and other components were built in the Teichert factory. 498cc and 598cc singles along with 750cc V-twin models were built until the Nazis arrived.
It appears that Gigant built machines for the gifted Austrian rider Martin Schneeweiss.
