Wedgewood first yr piece

[Parkie2]

We purchased from a large estate sale a piece we believe to be first year production. Not sure of all the other marks and there reference?
We believe this is worthy of sending to auction house?

If I've read correctly:
The "3DK" mark is a date code, and starting with a 3 indicates it was made from 1907-1924.
