Gary,
As always thanks for showing your nice find and love the style of your presentation cup. I believe the shooting school is now in Wiesbaden. I hope I'm right with that information.

jager,
Splendid trophies. Their wasn't a national meet in 1910. I'm thinking this is a shooting related trophy and not a hunting trophy and maybe won at a regional or local shooting meet. I've seen one just like yours and it was won by shooter Hans Gewiss.
Also their was a national meet held in Frankfurt 14-21 July 1912. Which was also their golden jubilee. Maybe your 1912 is from this meet. I can't read the writting on your very nice trophy to say. Bigger pictures would be needed. Thanks a lot for showing such rare pieces and really enjoy seeing them.
Houston is by all accounts the most renowned expert hands down in his field and is known all over the world. I bow to his expertise on all this stuff and you can take his word as gospel.
