I bought this years ago as an original. It's on vinyl with 'TAMPETE - 5444 - A' & 'MZ' in the run out.
(and 'Mick V', whoever he is, that once owned it)
A scan I've seen and it was selling as a boot was darker, almost bottle green.
Aside, the records that I have seen with a raised X in the run out have all been on styrene e.g. Shrine, Sylvia, World Artist etc
