vintage white ironstone china, 8 tea cups & saucers Regency swirl, 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 cups and saucers. 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 pieces from different years here, I think.
