With insufficient information, (see Polish Skoda Works) references of three PZ-Inz engines have been obtained: the 110cv Junior, the 130cv Major and the 90cv “Petersen” PS-II from 1933.

-Later, the Skoda Factory in Poland was nationalized as the “State Engineering Works, in Ursus, (see photos in PZL chapter).

-The company was located in Ursus. In 1933, they made the Petersen or PS-II (designed by F. Peter). It had four cylinders and gave 90 CV.

-From PZ.Inz. the 110 CV Junior and the 120 CV Major are known.

From Appendix 9: These engines were made by the earlier Skoda factories and later by PZ Inz in Poland. The Junior and Major models are mentioned without pictures in the main text. We discovered two models at the Krakow Museum.
