Help with origin of my Silver Bowl from China

[robertb]

Hi! I am after the origin and date of production of my silver bowl, manufactured in China.
I have attached a photo, please let me know if you have any guesses as to where it could have come from.
Many thanks!
Robert
Ps.: Here’s what ChatGPT had to say:
" The lower mark contains the characters:

銀樓
“銀” (yín) = silver
“樓” (lóu) = building or shop

Together, 銀樓 typically means “Silver Shop” – a traditional term used in Chinese-speaking regions (particularly in Taiwan or Hong Kong) to label jewellers or silversmiths.

The upper vertical line of text seems to be stylized manufacturer text, possibly including the brand or silversmith’s name and region (but harder to decipher due to artistic engraving). The stylized font makes it difficult to do full OCR, but this type of stamp is consistent with mid-20th century Chinese export silverware."

By Gemini:

The image shows the bottom of a metallic object with some markings. Based on the characters visible, here’s what appears to be written:

The larger characters, arranged vertically, appear to be Japanese. They read:

• 純銀 (Jungin): This translates to “pure silver.” This indicates that the object is made of pure silver.

Below and slightly to the right of the larger characters, there’s a smaller mark that looks like:

• 銀器 (Ginki): This translates to “silverware” or “silver article.”

So, the marks primarily indicate that the object is made of pure silver and is a silver article. These are common hallmarks found on Japanese silver items.
