Yes, not easy to find those Richard. The Gouby Date Style A variations are far more common than either of the 9 fonts in my picture which you have shown above. The style that I called 'New Style X / Narrow 9' is also a perfect fit with the protrusions that can be seen on the 1860/59, see picture now attached. When I described it as 'narrow' it was because the entire date is only 9 teeth wide, which is less than all style A variations I have ever seen, and also half a tooth narrower than Gouby Style B (with the smaller numeral 9). I wasn't meaning that the numeral 9 is narrow in itself!! Hope that makes sense.
It's another year that I must try to do some stats on from my 5-year ebay study. Problem is my wife keeps wanting holidays! 😉
