Thank you both 3sd and gmauchan. I had read on their web page that they didn't allow photographing anymore, which is why I started going round in circles wondering how to get access to their records.

But if they can provide copies I might try to contact them, getting a quote beforehand is always helpful.
I have a copy of Raphael's will and the NSW probate package (which Rosball very kindly photographed for me at our Archives). Thank you 3sd for the link to the death certtificate, not sure how I missed that on family search! I know the basics of his life: birth, marriage and death, but am trying to flesh it out a bit and saw these files and thought they sounded interesting, particularly the one above as it mentions his son as well. I don't know what he did in Cape Town - I have a report from a British newspaper in 1863 describes him as an "extensive merchant", and in Australia he seems to be an accountant or book keeper, although in his will he mentions his "operating instruments" which sounds intriguing. (His son was a doctor trained in London and immigrated to Australia). I wonder why the will was filed in South Africa, maybe he still had assets or debts there?
Anyway, thank you both once again!
