The model 1950 had the trim stock and the straight bolt handle. It was available in Europe up until about 1958, when it was renamed model NO (NOrmal ausfuhrung). I had a full stock 1959 NO in 9.3x62 that was near identical to my 1957 model 1950, also a full stock 9.3x62.

The model 1952 had the trim stock and the curved bolt handle. It was also available in Europe up until about 1958, when it was renamed the GK (Gebogener Kammergriff).

Some 1952's and GK's had the heavier stock with the black forend tip, but this was mainly at the request of Stoeger for the tasteless American market
