Hello,

It's fascinating to hear about the unique and beautifully crafted dresser/cabinet combination pieces you inherited as a wedding present from your grandparents in the 1940s. The fact that they were shipped from Stockholm to Washington, DC adds an interesting historical dimension to their story.

The "NK" (Nordiska Kompaniet) metal logo on the cabinet doors is a significant clue, as this department store represented many mid-century furniture designers. The modular design, with adjustable shelves, easily removable top cabinet parts, and interchangeable "feet" is indeed a smart and versatile feature, reminiscent of mid-century Scandinavian design principles.

While I don't have specific information about the designer or style, you might want to consult with a professional appraiser or furniture historian who specializes in mid-century Scandinavian design. They may be able to provide more insights and possibly identify the designer.

It's a remarkable piece of family history and design innovation. Best wishes in your quest to learn more about these unique cabinets, and thank you for sharing their story!
