Pewter pitcher marks and crest

Hi,

I inherited a pewter pitcher from family members. Anyone with information has now past. I have spent hours looking at pewter marks and have not found any definite matches. There’s also a crest/coat of arms with a crown inside the pitcher. I would greatly appreciate any insights you may have.
See below for my reddit thread on the pitcher. Note: the pictures of the crest link to a reddit discussing it.

Thanks,
Al
