vintage white ironstone china, set of 8 Regency swirl plates, Johnson Bros England

Vintage Johnson Brothers English made ironstone china, Regency or Snowhite Regency (I've heard this called either!).

This is a set of eight bread and butter or side plates, 6 1/4" in diameter.

A few of these have glaze crazing lines, but color is snowy white and glossy on all.

The marks look a little different, there's plates from different years here I think.
