My friend from willage where i find this helmet has a P.08 with Bulgarian markings.Im not sure
but in Clana was big barracs of JNA,the helmet is probably from there.Maybe JNA gets it from Bulgarians
afther the war (some kind of reparations),and there is little chance that it is there since ww2.In 1945
around Fiume and Clana were lot of Cossacs,Arab-legion,Chetniks,maybe some of them have those helmets.
