Two boxes and a shed load of shredded paper later.

Build quality is OK - certainly as good as most other presses out there. I'd grade it as above average Chinese manufacture.
Thinking about Spud's comment concerning the lengthened height of the dies with micrometer and some of the longer calibres, I decided to remove the vertical rod in order to check if it could be replaced with a longer one. This would prove to be an easy job; 30mins on a lathe at most.

Time and usag may prove otherwise, but at present I'm happy with the press. Not bad for only £42
