JohnAll,
I thank you very much for the kind words. It brings me great joy to share with you my collection and to know you enjoy them as much as I do.
John,
In 1912 the Kaiser awarded the GdK regiment a battle honors trophy. This meant that both officers and enlisted men would affix this trophy to the front of their cuirass as a symbol of honor. Prior to 1912 though, no trophy would be found on GdK cuirasses.
