Hello all, just thought I'd give a status report on the 'fact finding' mission I'm on. I have recieved no reply to either email sent (both R. Andrews and Ray Kimber). Will give them till Friday then will send another. If this fails to bring about a response I shall try the trusty pen and paper if I can get the relavent addresses. The purchase of the 'Black Book Vol 1' by Ben Duncan has been processed and should hopefully arrive before the weekend. If anyone has some other angles of approach for finding what research there is already out there on this topic I'm open to suggestions. Cheers Ben.
