Gearbox unknown, identify please

yes Michael is correct the gearbox is from the post war SKODA range..."In 1949 ŠKODA introduced a new type of vehicle officially named 1200 and popularly called Sedan. The vehicle was fitted with a modified four-cylinder engine originally developed in 1933. This unit was then modernised many times over years, and was used in a variety of models (440, 445, 450, FELICIA, OCTAVIA….)" I expect the gearbox carried over from the 1930's design (with improvements). anyone used one of these gearbox's in a special?

This could pe pre war skoda
