WMF is the abbreviation for Württembergische Metallwarenfabrik, which in English means Wurtemberg Metalware Factory. The history of this foundry is well documented.
WMF was created in 1880 after the successful merger of two Wurtemberg foundries, the Geislingen factory belonging to Daniel Straub (Straub & Sohn) and the Esslingen factory of Alfred Ritter A. On the handle there are the factory hallmarks. The image of a running ostrich set inside the rhombus with a two-line inscription WMF/G, which in turn is placed inside a partly-dashed arch. The size of the arch varies between 1.2 mm x 1.8 mm and 2.3 mm x 3.5 mm. This mark is a widespread one.A rarer (and more recent) variety with the ostrich making a larger step exists. The fraction "I/O" means the normal thickness of silver deposited on the surface of the base metal. The size of the "I/O" box varies between 1.9 mm x 2.5 mm and 2.2 mm x 2.7 mm. The one-letter inscription "N" means the use of nickel silver (Neusilber or Alpacca in German) as a base metal for silvering. The size of the "N" box is 1.8 mm x 2.0 mm.
The two-letter inscription "OX" ("oxydiert" in German, "oxidized" in English) means artificial darkening of the silver surface to a grey colour. The size of the "OX" box varies between 1.7 mm x 2.0 mm and 2.1 mm x 2.5 mm. The one-letter inscription "g" means "vergoldet" in German or "gilt" in English.
