Leon,
Any paint supplier that stocks PPG (formerly Dulux) has access to records that go back to the FE/FC era.
If you still have problems call PPG head office
http://www.whitepages.com.au/wp/search/results.jhtml?_DARGS=%2Fwp%2Fsearch%
2FsearchInput.jhtml.3 and they should be able to help.
If you still hit a brick wall contact me at
craig_alderson@yahoo.com.au and I'll chase it up for you. My brother was a Training Manager for PPG so he should be able to get the info you need.
Cheers,
Craig
