Bonna was a brand of the Lommedalen Ski Factory in Lommedalen, Norway. Ski jumper Narve Bonna started the Lommedalen Ski Factory in 1939 with Captain Earl Willoch. Bonna, who won a silver medal in ski jumping in the Winter Olympics in 1924, had previously worked for three years at Splitkein Ski Factory, where he developed his own patents. Bonna experimented with gluing laminations in a ski in Dalarna in Sweden in 1921. The skis were three meters long, with a birch sole and mahogany overlay, which made for skiing ease over the marshes and frozen water. The experience made him intent on making a shorter glued ski like this one, and it was more adapted to Norwegian ski touring.
