LP: 1974 Vertigo (Germany)
CD: 1995 Repertoire (Germany)
The LP comes in a fine gatefold. My copy is on the German "spaceship" label, and could almost be considered "common". True original UK Vertigo Swirls still hold value though. The CD comes with unique liner notes written by Chris Welch (who incidentally I saw on the tele last night as one of the participants on a show highlighting the making of Deep Purple's Machine Head).
