Toritoribe, Many many thanks for your help.
You were right with this '大行李長' being a rank. Army Logistics corporal I believe is its full meaning.
Now I've seen this pair of kanji (先生) crop up a few times and know that it means (Sensei) "teacher", is this what it means in reference to this flag or something totally different? So in the slogan,'先生之徳', that you have translated as "Your virtue" is that all that it means, or does it mean something along the lines of "Your virtuous teacher" etc.?
These kanji are also giving me some trouble(先生留名) I have checked my dictionary and the 2 red ones are utterly confusing me. What would their translation be in the above context?
Alternatively, could the two long strings of characters have a meaning in Chinese?
Sorry for all the questions. It's just a very interesting subject and want to learn as much as I can. Thank you.
