I don’t have much information except that it was my friends family for about 100 years.
You have a lovely Chinese curio cabinet made around 1930 / 1940 I believe. Its made of, usually pine and lacquered with heavy black lacquer. The carvings below are done by hand and add to the quality of the piece of furniture. These Curio cabinets are attractive to quite some collectors of jade or other small asian antiques. I believe if this simple but taste full cabinet came to a sale of auction it would fetch a price around the estimate.
