I'm not an expert so take this for what it's worth -
Another tape of purported Blizzard demos did in fact turn out to be fakes (basically multi-generation copies of the new re-recorded, remasters to give the appearance of hissy original demos).
However, these same two demos posted above are also posted at the Deep Purple Hub
and, at least according to the individuals posting to that thread, these two demos are the real deal with Bob Daisley on bass and Lee Kerslake on drums and they're the only genuine Blizzard demos in common circulation.
