Kunaver's mechanical metalworking workshop has been operating since 1928 in Rožna dolina in Ljubljana. Her machine park, however, has been changing over the decades. In order to be able to operate at all in this family workshop, individual machines were designed and manufactured by themselves, or purchased and reworked to fit the nature and scope of the work. Some machines from the first half of the 20th century have been preserved to this day, others have been sold. After the workshop was closed ing. Janez Kunaver donated some of the machines to the Technical Museum of Slovenia.
