vintage Delft pottery wall plate hand painted scene blue & white, crown w/ lion mark

Vintage hand painted Delft pottery wall plate with coastal scene – a cottage, a windmill, a sailboat. This measures over 16" across the rim, huge and heavy! It's in very nice condition, no chips or damage.

The mark is something of a mystery to me, I haven't been able to track down the maker. It's something similar to old Boch marks, though the crown would make you think Royal Delft or Royal Sphinx. It's clearly a lion, not a sphinx in the mark, though. No marks for dates or initials that I could find, and no stamped marks
