This hutch was purchased by a family member in 1986 at an import dealer's show in Pittsburgh, PA. She had lost it as a result of a divorce and recently regained possession. When purchased, there was provenance in the form of documents indicating that the piece was on exhibit during the 1903 Paris Exposition. Sadly, the documentation has disappeared.
As you can see, it appears to be a transitional Arts and Crafts cabinet with Art Nouveau brass fixtures.
All oak, the frames and other components are quarter-sawn. It's three pieces - the two side shelving units and the protruding center china cabinet.
Thankfully, there are two marks to help with its identification - a gallery stamp on the interior of the top drawer, and a manufacturer's mark on the back of the lower central cabinet. It's this mark I'm hoping to identify.
Any help with this would be greatly appreciated. I'm aware that the site is dedicated to modern and post-modern design, so please forgive the off-topic request. My hope is that, as some members may be geographically closer to its original source of manufacture, someone might be able to direct me in my search.
BTW, your site is splendid and I've bookmarked it for frequent visits. Having grown up with Scandinavian furnishings, and having recently (and sadly) disposed of them through auction, it's a delight to see the wonderful designs on display here.
