English Hallmark Help ? Boulton ?

Hi,
Can anyone lend a hand on the attached Hallamrks ? We have a large Epergne with 4 small bowl and one large center bowl and we cannot identify it. We believe it may be Boulton, but not sure.
The marks read as: DP (What Looks Like A Bird Or Standing Lion) S and then a Sunburst as shown in a arched window box.
Any help would be greatly apreciated.
Thanks,
Dave :question:

I have no idea what the marks represent, but they are definitely not Matthew Boulton’s marks. Your picture is too out-of-focus to see exactly what the other marks are.

Thanks,
Ihave posted a clearer picture for review.
