Could this be a Hung Chong mark? If not, can you help identify?

Hi,
Can anyone help me identify marks on a vintage/antique hat pin with an unusual long length, resembling late 19th, early 20th century styles. The pin part tests silver. Top section seems to be gold plated.

Is this a mid century export mark; or could it be Hung Chong? Considering it's a hat pin, a bit unlikely, but my research tells me Hung Chong produced other small personal items, and the floral engraving when zoomed-in on details is quite similar to some you see on their card cases.

Many thanks in advance.

Hi,

It's Hung Chong & Co. of Shanghai.

Here's another example with the same Chop mark:
