Saw article about women in bosnia that had specific style of tribal tattoos so that got me wondering if there are any preserved archives of what tattoo a typical serb would be sporting before culture shifted?
First of all you must understand that many Balkanic phenomena are still terra incognita. We do not know their origins, their meaning, practically we don't know anything. Tattoos of the Bosnian peoples are one of those phenomena. There aren't many works, and they were written between mainly 1889 and 1930. They suffer from many faults, primarily superficiality.
As for the Serbs, the only mention I've found is the work of Leopold Glueck, which you can see here. He says that there were some tattoos among Bosnian Serbs, but that they were not as rich as those of the Roman Catholics.
As someone who researches Early Modern Balkans, I must say that I did not come across any mention of tattoos among the Serbs, although I'd be glad to stand corrected.
PS Do not take claims of (anti-)Ottoman origins for granted.
