Ironstone Plate

Could you please provide information about this plate, maker, date etc. The is an impressed mark on the base 'Ironstone'. I think Masons invented the term but I believe it was copied by several other companies. There is no country of origin so I presume it is mid 19th century.
The decoration is not typical Masons. The rim is a burnt orange colour.
Any ideas?
Diameter 19cm
   

I'm doubtful you'd be able to add to a general description of 'Victorian Ironstone chintz transfer printed and hand coloured plate'.

looks like crown ducal

but that's just a guess

Hi Carlos, thanks for your comment. I think Naomi has hit the nail on the head, it is going to be difficult to id and date exactly unless you are an expert on Ironstone ceramics.
Crown Ducal is the name used on ceramics made by A.G. Richardson and Co., Ltd., of Tunstall and Cobridge, England. The name has been used since 1916. Crown Ducal is a well-known maker of Chintz pattern dishes but quite some time after this plate was made..

Don't think you will be able to find the exact manufacturer, just a Staffordshire piece
