Hard to tie this one out – would be happy to hear from others – but this stein was a part of an ADVANCED porcelain insert stein collection that centered around Milwaukee and Chicago. Sam Trimmel is the father of Gustav Trimmel who was a partner for several years with Charles Mader whose name is synonymous with the famous Milwaukee landmark - Mader’s Restaurant. Mader operated a saloon at 7th and Juneau, where he also lived, sharing the business with Henry Adler until about 1916, when Mader takes Gustave Trimmel on as a new partner. (Later, the place would operate as Trimmel's Cafe). Interestingly, in 1915, the City Directory listed Mader as living at 7th and Juneau but working as a bar manager at Trimmel’s saloon at 309 3rd St. That same year, Mader became an American citizen and Sam Trimmel, Gustav’s father, was one of his witnesses. Was “The Hungarian” a nickname, a brief name of the establishment or something else… No idea… Excellent condition to both the porcelain insert - the stein itself does have two stress fractures in the base that are kind of neat and a long back scratch midway up - about 7 ¼ inches tall including the thumb lever. This is a particularly rare example of a porcelain insert stein.
