Well. It sez on the site that there are 3 in that series.....
"Not far from the headquarters of the Böker Manufaktur in Solingen, Schloss Burg on the Wupper is the landmark of the Bergisches Land region. It is also one of the largest castles in West Germany and the largest reconstructed castle in North Rhine-Westphalia. The glorious history of Castle Burg is inextricably linked with the Duchy of Berg and the Counts of Berg (Haus Berg 1068-1225). We took this opportunity to dedicate a razor series to the three Counts of Berg , symbolizing parts of the three counts' lives and reminding us of the considerable possessions and power of the counts with their impressive 24-carat gold ornaments.
The last Count of Berg, Engelbert II, was also called Engelbert I, Archbishop of Cologne. With his murder Berg went over to the House of Limburg. This splendid razor in 7/8 inches shows Engelbert as Archbishop of Cologne. The degree head of this sound-ground blade made of the best Solingen razor steel and the curved blade back in combination with a handle of the finest horn document the highest elegance and unique quality. Including certificate of authenticity and elegant presentation display with individual serial number."
