Otto og Mattis Design

Being one the only private military design companies from Norway. It has developed many intresting and unothodox designs over a period of time. Being founded in November of 1923 it started with developing vehicle equipment on for Troll Bilindustri. And in 1929 it purchased the property that would become its small but intresting vehicle factory. This is when Mattis Jaur was looking for investors and designers, after some time he came in contact with J. Walter Christie and a contract was signed to design vehicles and concepts in quarters. This ment that everytime Christie was in Norway, he would be designing and coming up with ideas for the company. A great addition to the design process was that Mattis had military experience and still knew people in the military including ones in sweden aswell. This would be great to guide Christie in the right direction.

J. Walter Christie Worked with Otto And Mattis on a Few Designs, This ment that Christie was in Norway for periods while working on said designs.
