Doesn`t look like any kind of a mark at all !! Initials are usually the decorators initials !! That is how they got paid,, they were paid according to the number of items they completed !1 The number is the mold number !!
Can you take a pic of the creamer upright with the lid on ?? Need to see what it looks like !! Likely an import that would have had the sticker where the gold patch is !!
