In 1931 Moscow
Avtomobilnoe Moskovskoe Obshchestvo (AMO, Russian Автомобильное Московское Общество (АМО) — Moscow Automotive Enterprise) truck plant was re-equipped and expanded with the help of the American A.J. Brandt Co., and began to produce a new truck with designation of AMO-2. AMO-2 was intended as a replacement of the previous
AMO-F15, the first Soviet truck ever built (it was a copy of the Italian
Fiat F-15).
Soon
AMO-2 was improved, and new models
AMO-3 and
AMO-4 appeared. In 1933 AMO was rebuilt again and renamed into Factory No. 2 Zavod Imeni Stalina (or Plant of Stalin's Name, abbreviated in ZIS or ZiS) and in Summer first prototypes of the new ZIS-5 appeared.
