Since 1998, or even a bit earlier, David and I have been assembling capacity marks that we could attribute to specific manufacturers, and have found that capacity marks are unique to any given factory. Therefore, they can be used to identify the manufacturer when other means are unavailable. By unique we do not mean that only one capacity mark was used by each factory, but that any number of marks, used by any given factory, were used only by that factory. Manufacturers were identified either from markings on the stein itself, or from identification through factory catalogs.

While many of these marks may appear alike, no two are identical, but close attention to detail is still required in some cases.

If you have a mark you think should be included in this data base you can contact us by clicking on either of our names above.
