As far as I know just 50 DJ copies were made - I don't believe any were trashed, unless they made the issues and trashed them?????
Here's some more info on the unreleased 45's on Grapevine 2000 including info on Test Presses, DJ Copies, Issues and a full label listing https://www.soulmusic.co.uk/grapevine_article.htm
