antique vintage flow blue china serving pieces, large platter & covered bowl or tureen

Unmarked antique flow blue china platter and covered bowl, ironstone or semi-porcelain, almost certainly Staffordshire china. 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.

The platter measures about 14 1/2" long, and the oval bowl measures 11 1/2" across the handles. Both of these pieces are in very nice condition 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 these pieces. There's good flow blue throughout but very little browning or foxing spots, and no staining from use. The gold looks very good, these have had very little use.

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 one of the dozens of other makers of English flow blue china. Without a maker's mark, it seems impossible to tell!
