Quote:An Austrian car, the PA 1, was built on an Austro-Daimler truck chassis in 1916 but was used very little. In design it was much inferior to the 1904 car built by Austro-Daimler. A commercial car, the Romfell, was built in Austria in 1916. Although an excellent car for the period, it did not go into production.

Peace treaties forbade Austria the use of any armored vehicles except for police duty, and none were built. Major Fritz Heigl, the famous Austrian tank authority, kept interest alive, and, in 1926, designed the M26, a dummy armored car for instructional purposes, of which several were built. In 1932 Austria purchased several used Skoda PA 2 cars from Czechoslovakia and modified them by adding a small observation cupola above the main turret.

Beginning in 1933, the Austro-Daimler firm (later Steyr-Daimler-Puch) built several interesting armored car types. By 1935, the former Central Powers had renounced the treaty limitations, and this firm began producing vehicles for the Austrian Army and commercially for sale to foreign countries. The ADGZ car was adopted in numbers by the Gendarmerie as well as the Army. Fiat-Ansaldo CV3/33 light tanks were purchased from Italy. The infantry were equipped with a small wheel-and-track machine-gun carrier of several models, perfected by the Daimler Company.

After the Nazi invasion of Austria, German equipment was substituted. Known Austrian vehicles are as follows:
