Rudolf Gundlach and his periscope by Michał Łakiszyk, class 1a

In 1934 Rudolf Gundlach constructed a reversible tank periscope which without the change of the position still had the visual field of 360 degrees. This invention is applied up till today. It was patented in France, Great Britain and Sweden. German and Russians stole plans of the periscope away.
