could you specify "gibberish" or why you come to call it "gibberish"?
Also in order to determine anything, the sizes / dimensions of the yathagan might be helpfull....
Tip: perhaps my articles in this forum on the Ottoman Bosnian cold arms ( amongst it languages on blades of bichaqs and yataghans and items in Balkan museums) will assist you further....
FYI: the Fez shown on the pictue might either be from :
1. the Bosniaken K.u.K Infantery Regiments I to IV
https://en.wikipedia.org/wiki/Bosnia...inian_Infantry
or
2. the 13. or 21. Waffen-Gebirgs-Division of the SS Handschar
https://en.wikipedia.org/wiki/13th_W..._(1st_Croatian)
https://en.wikipedia.org/wiki/21st_W..._SS_Skanderbeg
or (what is recently often seen) a recent copy made for either historical enactment or fake copies of the original ones
an indication might be the pet-badge or holes in the Fez where these badges used to be ( enclosed some pics of the K.u.K. Habsburgian ones)
