Curious who this is made by

I just bought this bedroom set, I feel like it’s pretty old. It’s been painted, I’m not sure yet of the original color, the pieces are extremely heavy and well built. There are also two night stands and a desk/vanity. I can’t find markings indicating who it’s made by on it anywhere. Curious if anyone knows anything about it or where I can find information about this type of furniture. Thanks in advance!
