hi it is jonathan barnbrook, the designer of the limited edition vinyl.
just to clear things up about this: 530 copies were printed and stamped. 30 were kept back they were for myself, metamatic records, the artists and cargo. the rest that is, 500 only went on sale. the ones that were kept back were a few of the early ones and some random ones all the way through.
with something like this the edition is very carefully controlled. there are no duplicates, and no numbers beyond 530. i know because i did it all the stamping and numbering myself. i marked each one when it was stamped 3 times. see photo in this link:
http://twitpic.com/dreo3udear postpunkmonk. the image used is not your cover. it was a mock-up done before the cover was printed. the numbering is different. your real copy will have a dash at the beginning rather than a zero. also the stamp for the main title is different.
hope that clears up any confusion with the numbering as i was very careful to make sure everything was accounted for and correct.
