The flag is documented by the company website, Nüsse’s table flag and a July 2006 photograph. Borussia Dortmund’s funnel was photographed in September 2005. Bought in 1993, the vessel was named after the owner’s son’s favourite football team and painted in its colours: a black hull with the remainder sulphur-yellow.
Rudolf Schepers, born in 1957 and grandson of the earlier Rudolf, captained family vessels under Thekla Scheppers K.G. He left in 1989 to form Rudolf Schepers K.G. and bought his first vessel in 1990; Lloyds dates formation to 1990.
