Large Chinese Export/Satsuma Plate?

This plate is a bit of a conundrum. I bought it with some others at auction and so the label on the back was placed their by the previous owner/seller. The stamp/signature on the bottom is definitely not recognisable and so could be an English copy as the label suggests, however, I wonder if it is Chinese export or even Satsuma Mille Fleur - I cannot vouch for origin.
The plate is however, very beautiful and has some age as there are one or two rust spots beginning to break through the surface and there is also some slight wear to the gold around the edge. If anyone knows anything about it please let me know. It looks hand painted and measures 24cm in diameter.
The plate depicts flowers on a gold background with two dragons that look as though they are walking on clouds.
Whatever the age or origin, this is a very beautiful item.
Please note that I will be unable to dispatch this item until Thursday 25th July when it will be sent 1st Class Recorded post.
