Some years ago I picked up the depicted Preussian medal bar, together with the certificate of the Zentenar-Medaille 1897.
The certificate is made out to a Eisenbahn-Zugführer from Braunschweig.
The group consists of: Kriegsdenkmünze für Nichtkämpfer, Allgemeines Ehrenzeichen 2. Klasse, Zentenar-Medaille 1897.
What puzzles me, is de coloration of the AE2 ribbon. Half of the ribbon visible is white & orange but the other visible half is (discolored?) white-ochre. As far as I can see, the bar has not been 'doctored'. The piece of the ochre stripe which lies under the overlapping ribbon with is also ochre, thus there is no discoloration due to age or sunlight.
Does any Gentleman have a clue?
