Antique shelf

I bought this shelf from a friend a couple years ago for $200. Cannot find a company stamp or logo on it anywhere. Has beautiful, very detailed craftsmanship. Has never been refinished, original hardware and mirrors. Has a couple of flawed places but barely noticeagle. It belonged to my friends mother and she had when she was a baby. We believe it's at least 70 years old but not positive. I've been told the wood is teak by person and dark cherry by another person. Curious if anyone may know anything about this.

Good
