This pair of blue & white plates are English. They have a traditional Delft Sailboat Scene and are marked DELPH. There is also an English Registry mark 114786 which is circa 1890. There are no chips or cracks. There appears to be a repair to one of the plates. The other plate has a manufacturing flaw on the back. Still very nice collector plates.
