D.R.G.M. 419784 stands for Deutsches Reichs-Gebrauchsmuster. This was Germany's official "utility model" or design registration system, similar to a short-term patent or copyright protection for the item's design or functional features.
The neoclassical design (oval tray with laurel border, balustrade gallery, urn-shaped central taperstick) was popular across Europe, and German manufacturers often copied or adapted English Regency/Victorian forms for export or domestic markets.
This is well made and heavy. Weighs almost 6lbs.
Dimensions 15" x 9"
