Thank you.
@Sandor: You are right with the banner in some parts. The elements are Burgundy but it is a German Imperialist banner from the reign of Maximilian I. around 1500. When Maximilian married Mary of Burgundy (daugther of Charles the Bold) in 1477 he took over the heraldic signs of Burgundy and used them by himself.
He also took over what was left of Charles ordonnance companies and formed a unit of heavy horsemen called the "Welsche Garde" (the "foreign guard" in modern english, which means that the members of this unit not came from German countries). The Welsche Garde served for example in the Schwabenkrieg 1499 in South German and the Swiss.
In the Schilling Chronicle of Luzern a banner of this kind is shown two times in connection with the Schwabenkrieg and the treachery of Novara in 1500. Other Banners of this kind but without colours are shown in the book "Weisskunig" which tells about the live of Emperator Maximilian I.
