Can anybody recommend a good stamp catalogue website that is up to date? I am mainly interested in Aust pre-decimal. I have done a bit of Googling but they all want to sell me something and, I just want information. I have been into the cupboards and found a heap of stuff I had forgotten about and want to arrange things into some sort of saleable packages. I have had a few Stanley Gibbons Catalogues over the years but would like to get the info for free for a change.

Simmo.
