Thanks everyone, yeah Wolfy, might keep it for a while or ever, whichever comes first lol.
Thanks for that too GP, I'll check it out. Nice piece that nugget brooch. I found a few more links to some his works also, there was a gallery done by the National Gallery of Australia called "ut of The West" on some of the early jewellers in WA's early goldrush period, which are quite interesting. I called the NGA research library today and spoke to the librarian, luckily while talking to her a curator came in and she asked if I could send him some pics and info to get a better picture on rarity and value. So I sent the email with pics and will await his reply. They asked too if I may be interested in selling it after apraisal.
Rod, it sure does, really happy with it, love our Aussie history, hopefully it's a rare find.
