then you probably saw one of the many SQ versions that weren't marked as SQ, as per the discography.
If it was then , that bodes well for the album always being encoded .
BTW the copy I had seen was sealed and was a Bellaphon Bacillus release.
You should note that I had a copy of the 2nd album ...UK version...and the stamper on both sides were The Bellaphon Bacillus ones , however the number on one side was vacant of the 'Q' , to confirm quad.
