American of Martinsville early piece?

I bought this cabinet years ago. I find it interesting that American of Martinsville did not make Dining Room pieces until around 1920, so my piece might be from around then. Their logo has changed slightly over the years, from what I have researched. The older pieces for "home" not "business" tend to bring much higher prices. The piece that I have does not have the slats or pulls known to the more recent American of Martinsville furniture collections, which leads me to believe this one is much older. My question is that searching Google for any item by this company, I cannot find any other like it made by this company. That has me wondering if it is rare, and what it's value might be. The lady we bought it from said it belonged to her great-grandmother when she was young. There are a few screws on the side, and a plate on the back, holding the pieces together, and I believe those were added later, unless I am wrong. Furthuremore, I am unsure what kind of wood my piece is made out of, or what its value would be.

American of Martinsville

American of Martinsville has an extensive history and is still producing furniture today, but here's their streamlined story with the pertinent parts for a mid-century fan: Founded in 1906 by Virginia tobacco producers, American of Martinsville furniture line consisted of only bedroom furniture. In the early 1920s the company added dining room furniture and began to expand its offerings through a number of diverse styles. In the 1950s, as the company grew, so did American of Martinsville's reputation for styling and design leadership. With products in almost every design, the company continued to expand its offerings to cover the living room, in both wood and upholstered furniture.
