8in Sterling Spoon, cant identify marks, thanks for any info

Hi, marks seem to be to squashed-worn to make out what they are: seems to be, … a “P” with something else … a “G83” (??)… a leopards head (at the end) …some makers-mark after the “P” mark, with maybe a W and some other hard-to-figure-out letter…any ideas on maker?, thanks in advance for looking into it, regardless of results…
