I answered this a few weeks back. There is a cutting lathe whose cogs cab be switched about to cut from the centre outwards.  Sent from Samsung Mobile Maarten Bouwes <maarten@bouwes.nl> wrote: Interesting. <shame> I have always asked myself how they made it<unshame> So, having seen this item, the question now is how did they made the backward Madrugada. That couldn't be coincidence!

Maybe someone could enlighten me? In ther meantime a big thanks go to members of the list who have helped me fill the gaps in my KLF collection with good quality copies of Lost Sounds Vol 2 and The White Room rather than dodgy fuzzy ebay copies!? You know who you are and I thank you again...but I still don't know what a "stamper" is! ?
