In 1901, Theodor Wieseler began an expansion of his business outside of Nuremberg. The company is still in business today, as one of the oldest, and largest, wholesale co-ops in Germany.
Today, the company is headquartered in Essen, Germany and is called "Die Nürnberger Bund Produktionsverbindungshandels GmbH."
Here we have a Theodor Wieseler, (T.W.) marked, 2.5 liter, Nuremberg Tower. Note the lower case, cursive "b" decorator initial and that the "geseztlich geschutzt" mark is the same size and font as that used on HR steins.There are no model numbers on TW steins. Note the markings on the HR, Nuremberg Tower seen directly below.
This is the 1.0 liter version of the TW marked Nuremberg Tower. While there is no decorator mark on this piece it is marked with HR's "gesetzlich geschutzt."
This 1/2 liter, "T.W." marked stein has none of the regular Freising/HR base marks, but it does have an HR "type 4" capacity mark.
