Hi Dave,
Another interresting combo. I will try to find something.
First when we see such combo it is difficult without having Schwarzburg rolls. But the other combo is interresting.
First there is no centenary medal but we have a long service medal. Each time I see that I think immediatly to a young officer who begun his career as a NCO and who became officer with the time.
He made his career and won the KO4. If he were a pure Prussian officer, he should received first the RAO4 and then after the KO4.
Our man probably finished his duty just before the WW1. He was then called back during WW1. He won both EK, HHO3X.
And about the SE2X ? It is a very high grade. Our man finished the war, if he has survived , probably with grade of Major. And like he was born, or served or what else with Schwarzburg connection, he received this cross.
That's my explanation, IMHO
