About the original – the very first release on the Kustom Records label:
– DEEP PURPLE H-BOMB – # ASC-001; matrix numbers on vinyl: side1: 2001-A/B
“This is the original LP pressing from 1970-1971. It has a picture sleeve which has a plain white back. It comes with its original plain paper inner sleeve. The record is pressed on thick vinyl & has grooved labels.”
“The second pressing [of the European bootleg Space Vol. 1/2] was called “H-Bomb”, which a more professionally produced single album which lacked “Mandrake Root” and also had slight edits to the other songs. “
