“Dutch” style dining room furniture

I am looking for more about the production of this specific line of black furniture with gold metals in Portugal. My grandparents had a room full of these, grandparents of my friends, family, family members across the family, and further set a set, and I see in OLX etc sellers from various parts of the country, so I suppose it was a fashion around the country around the 1940s.

In online sales are often identified as a “Dutch style” furniture, but I spent the last hours looking for historical references that would help me to realize how our grandparents across the country bought the same type of furniture. I deduce that it would be from some kind of catalog that was replicated by local carpenters, loved to know more about this.

My grandparents are no longer alive, and my mother thought it was family panca to have the cousins and aunts all the same kind of dinner furniture, until we see that there are ads throughout the Portuguese net, including beyond the black version with gold metals, there are also some in brown version, but it will not be the original color.

Nor do I notice the connection with the “Dutch” they use to describe in the ads. I tried to look for also with the GPT but I could not indicate any specific source about this line.

If you recognize this specific line of furniture, if your family members who bought them are alive, I was very fond of knowing the story of how they bought them. Thanks!
