English Japan Pattern Plate c1820

I bought this plate on eBay thinking I would easily identify the maker when it arrived (there was no photo of the back). However, having gone through my books on all the major makers of this type of pattern and scoured The Saleroom plus multi Google searches I’ve not found this pattern.

It is a Japan pattern from c1820 and totally had painted. The reverse is stained and has some grit. My best bet is Coalport but does anybody recognise the pattern?
It measures 9.25” 23.5cm

thanks

John

 

Is there something here?

 

No

it’s just a smudge of the blue

 

I was looking at the mark on the edge between the two blue smudges. Almost looks like the letter "M" and a few others. Could be just dirt though.

 

No there’s no mark unfortunately. Thanks for looking.

 

Well if it's any help, Coalport from back then is STARK chalky white and the footrims tend to be very angular rather than soft-cornered ...it looks a bit Derby-ish, but without having it in hand, well, you know ...

 

Yes it does have a bit of a Derby feel to it. I’ve got a Derby cup and saucer with a similar body.

 

I'm assuming you have been searching English Imari patterns, yes?

I don't know but did find this listing for a teacup and saucer that I believe is the same pattern. They say Coalport but that they've seen the same pattern by Derby and Spode. I did browse through Twitchett's Derby book but the only two Japan like patterns shown aren't this one.

Interestingly the same seller has the same pattern as a three piece set that they say isn't marked but actually appears to be marked on the inside of the foot rim.

Thanks.That’s the pattern. It looks like an R in the foot rim.

 

Yes English Imari and Japan

 

Looking back at the other listing it is marked on the foot rim as well though doesn't appear to be an R. Perhaps it's just a painter's mark.
