Both with ochre...
I've posted this to show what can be found by trawling through eBay shop seller's stock. I found this in a US based one. The variety (missing ochre) can be seen on the right hand stamp, on the Queen's sash. Notice the lack of brownish colour.
Listed in Gibbons Hong Kong 4th edition as SG210a (sorry folks, don't have a Scott's at hand). There's no used price only mint; £325. Bit of a scruffy copy but for about US$8, I was more than happy. This is the first I have ever seen on this top value, which of course was not spotted by the seller:
