Surfing the web, I just found 3 compilations in which I took part, but never received a copy. Two of the labels have promised to send me copies... the other I wasn't able to track down. If you care, check the Brutum Fulmen discography for: 4 Sides a Circle (AMK 4xCD3), Sicktron (Black Arts C90), and Entartete Musik (Entartete 4xC90).
