Myott Dinner Set

[Fiona]

Hi Ive recently inherited a Myott dinner set in mint condition and was wondering the history of the set.
The dinner plate is stamped with number H.W.339 also next to the Myott stamp on the back is a hand painted green "K". Also above "H.W.339" is a gold slash above the 9. The set includes cups, saucers, dinner plates, bowls, a serving dish as well as the small plates that go under the cup and saucers.

Any help is much appreciated.
