This is a small size model of a sheet press for rolling hot steel. The model is labeled in Polish as “50 lat Walcowni Goracej Blach 1956-2006” and is from the Nowa Huta section of Krakow Poland. I believe that the model may have been made to commemorate 50 years of steel production after Stalin's death and the less Soviet controlled government in Poland.
The model consists of a heavy metal housing with two brass rollers mounted on a marble base. Size is about 5” X 4” X 3”. Weight is about 5 lbs.
