Some information on Streamers used. From 1835 those Units who had existed for 100 years was awardet a "Säkulär-Band" which for Prussia was in Black and White (Prussian livery colours, other states had their Colours like the Blue and White of Bavaria), it was inscribed with the text Errichtet (Raised) and the year of the raising of the unit. On the lower part was Royal monograms and on the knot which tied the streamer to the pole was the year of the raising and the year when the unit achieved 100 years for example 1789-1889.
At the turn of the Century 1800-1900 all Prussian Regiments was awarded the "Jahrhundertwende-band = Turn of the Century Streamer". This was black with two white stripes in the middle and ending in tassels. The streamer was tied with a knot and formed two bands hanging down, both having plaques in the lower part, the fist bearing the monogram of Wilhelm II below a Imperial Crown,the backside carrying the date 1 Januar 1900. The second was the like but the monogram was ensigned by a Royal Crown, the two types denotes the dual title as German Emperor and King of Prussia. The other States of the Empire followed suit and introduced Turn of the Century Streamers in their own colours and emblems.
