Branko Peshelj was a member of the Croatian Peasant Party and advisor to its long time leader Vladko Macek. He was also an American government employee and informant to the FBI. Combined this makes him one of the more important Croatian emigres during the post-Second World War period.
However, only a portion of his FBI files were released as part of Interagency Working Group efforts. Back when I was doing archival research, I pressed the NARA staff to release for more of his records. This summer, I achieved the success seen below. I was also informed another of Peshelj's FBI files was being dispatched to NARA. While this will force me to miss work to hop over there and acquire it, it just seems tacky, after all my bitching, not to grab it.
