G Jones and Sons plate

[dpsmpt]

Hi there - I've recently obtained a plate that I beleive has King Nicholas' child on it. However after researching online, the image seems to look more like Edward VII as a child.

I can work out from the markings on the back that it is made by George Jones and Sons, the marking was apparently used between 1874-1924

I have searched google for hours and found nothing, so I was hoping maybe some professionals could help me find out a bit more about this peice.
There is also a mark that either says H6 or 9H depending on which way around you look at it!

Many thanks

Please post a pic of the back with marks.  Take pic in a naturally lit room without the flash.
