Lohr am Main, Bavaria.
Zinngießerei / Pewterer.
Known dates: circa 1890's to 1920's.
There was also a Richard Staub, also a pewterer and also located in Lohr am Main. It is unclear if this Richard Staub was related to G. Staub, but it would make sense, perhaps he was the son of G. Staub and perhaps he continued the company at some point in time under his own name.
G. Staub purchased stein bodies from:
Reinhold Merkelbach
Richard Staub's pewter mark is seen on a glass stein made in the first half of the 20th century by the
Sächsische Glasfabrik.
