That is a beautiful uniform. This pattern of Polrock was worn from 1867 to 1886 when it was replaced with the Preußen Dunkelblau Waffenrock. These were tailor made, so it must have been expensive, and far too intricate to be discarded by a family. It’s wonderful. Could we see the Braunschweig Kepi as well? I have searched many years for an officer kepi without success.
