The text is 'KORT STEMPEL', and the double '1' is the stamp number.

This stamp was in use in Norway c. 1900.
The text is 'KORT-STEMPEL'. The stamp number here is '33', this was used on an imported pack.
This stamp was in use in Norway c. 1920.
The text is again 'KORT-STEMPEL', but the crown differs, and the coat of
arms has a different form. The stamp number is '1' again.
These are stamps that were in use c. 1930 to c. 1940.
The text is always 'KORT-STEMPEL' and 'Nr. 1', but the crown and the shield look a bit
different on each of them.
