There is an excellent article by Emir O. Filipović in which you can read about herzog Hrvoje Vukčić Hrvatinić, who spent a large amount of money to present himself in Buda, or King Ostoja, who forgot his regular royal duties because of the preparation for his trip to Hungary etc. Viteške svečanosti u Budimu 1412. godine i učešće bosanskih predstavnika (Festivities held in Buda in 1412 and the participation of Bosnian magnates). The same author has a book Bosansko kraljevstvo (Bosnian kingdom) and from page 489 to 537 you can find a great deal about knights, military equipment, hunting, etc.

Nice overview of Bosnian knight culture is Dvorska kultura – viteški turniri i igre (Court culture - knight tournaments and games) from book Konj u srednjovjekovnoj Bosni (Horse in medieval Bosnia)

Another one is Bosanski stil jedna od osobenosti bosanskog srednjovjekovlja (The Bosnian style - a particular feature of the Bosnian middle ages) by Vesna Mušeta-Aščerić in which you can read about ad modum bosnensis - jewelry, belts, pottery, silverware, Bosnian shield (scutum bosnensis) and other weaponry.

edit: f you are interested in the history of women in Bosnian middle ages there was a round table Women in medieval Bosnia in 2012 (I think) but published in 2014. There you can read about Bosnian slaves on a slave market in Dubrovnik, court ladies, breastfeeding for hire, etc.

There is also book by former National museum director Mirsad Sijarić called Hladno oružje iz Bosne i Hercegovine u arheologiji razvijenog i kasnog srednjeg vijeka (Cold-steel weapons from Bosnia and Herzegovina in the archaeology of the high and late medieval periods) in which he analyses about 1,350 swords, spear-heads, maces and arrow-heads found in Bosnia and Herzegovina. Unfortunately, I don't have a pdf, but you can find it in the museum or national library.

p.s. I have a BA in the early medieval history of southeastern Europe/western Balkans so PM me if you want to know something about that.
