Greetings. Yesterday I visited Koblenz, only about one hour away, and my wife surprised me by taking me to a German military museum. There were hundreds of items of interest in this museum which covers the history of the German military. Their firearms section was superb.
I have attached a few photos for your enjoyment. Sadly, everything is behind glass which makes it difficult to get a great shot but perhaps these photos will, if you are ever in town, make you want to visit.
