Here’s an extremely rare SA Beer Stein with zinc top.  There is a large brown SA painted under the glaze.  This particular example is named to Jakob Ziegler serving Sturm R 11/6.  The mug is sized at .5L.  There is a small chip on the underside of the mug (see picture) and the top is a little loose around the mug handle (hinge is very solid).  The mug is in excellent condition considering its age.
