Yes still looking. Have you got anything?
I have rung around a few Sydney paint outlets and none lead me anywhere. One I did find that told me over the phone they could mix some couldn't assure me of a decent match when I brought the mower deck for them to have a look.

There is an Italy based online company called Vernicispray who sell a yellow gold hammer tone colour that looks to be a great match who told me over the phone they don't deal outside the EU and said I would need to nominate an address in Europe to send to.
I also discovered a metallic non hammered paint in a can made by Dulux that is a very close match. I might have to use that for now.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
