In this page, you can search the punches by the number that Erling Skaug gave them and based on the shape they have in the icons of every entry. You will be able to see a scaled view illustrating the dimensions of those punches of which we have digitized photographic material, that allowed to extract the data.
The figures below represent the two grids which were used for a scalar representation of the punches. The black grid on the left was used for all punches up to 14 mm while the red one was used for those with larger dimensions. Each notch represents one millimeter.
