This is true, Naval is most often overlooked, and it is unfortunate, as it is very cool, and one of my favorite things, not just German, but in general. I particularly like cap tallies, they are good for a person such as myself, for the reason that they are easy to display properly, and there are of course many to find and collect. Right now I do not have any tallies on their own, however I have recently acquired a full Tally Cap from S.M.S. Hohenzollern, that was of course the Kaiser's private yacht constructed in 1892, (that I will post on here at some point.)
Naval items also have a particular importance to me, because it is what actually got me into this hobby. When I was young, I had a fascination with everything that had to do with maritime and nautical matters, and as such found a natural Naval interest, witch led to my interest in this hobby, and the best part about that, is I have an early start on things, I have only just begun.
Anyhow, a very nice collection you have, and I really like the way you have pictured them.
