HALLMARK HELP....one more

This is a ladle…first mark is very hard to see…looks like a crown or even star shape. Middle lion and last looks like a D date stamp. Is marked STERLING then Thos. W. Purdy which I am guessing is the merchant and has nothing to do with the maker? Any help as to maker, where and date is appreciated.

Thanks

I can’t identify the manufacturer but I can say that it is almost certainly an American mark.
