Makers ID for late 18th C China Export Silver Spoon

[AussieSilverStandard]

Hi folks, I came across this spoon in a lot of Sterling & Continental Silver spoons I bought at auction. It's beautifully made, the bowl is hand beaten, the handle soldered to the bowl & has the most naive floral pattern on the front.
I know quite a bit about the history of China Export Silver but very little about the makers/sponsors who's marks appear on it.
Any help greatly appreciated.
