antique flow blue china plates set of 10, unmarked English Staffordshire 1880s?

Uncommonly large nice set of ten matching plates, antique flow blue china, not marked at all that I could find. They're ironstone or semi-porcelain, almost certainly Staffordshire. 

This is a set of ten plates - about 9" in diameter - with very minimal wear or damage, it's amazing to think that these are almost 150 years old!

There is crazing, and a few small glaze pops at the rims of most of these pieces. There's good flow blue throughout (noticeable on both the fronts and the backs of the plates) but very little browning or foxing spots, and no staining from use. The gold looks very good, these have had very little use.

We'd guess the age at about 1880, give or take 10 years?  Without question before the US tariff laws of 1891, when law would have required export pieces to be marked with the country of origin.

They are a blue spray or floral bouquet pattern, gold edges and decorated with hand-painted gold. Possibly Johnson Brothers? or Grindley? or maybe one of the dozens of other makers of English flow blue china. Without a maker's mark, it seems impossible to tell!

We loved this set from the moment we saw it, as we've never found so many pieces in a matched pattern before, and don't expect to ever find so many again.

It's out of the estate of a lady who collected some very lovely, very old pieces from farm and house sales about 50 years ago, in what is now the north-western Chicago suburbs. And that's all we know of it's history.
