Sam,
That's what's known as "clockface" type numerals, in which no matter what their position around the rim of the case, they show as being in the correct orientation for reading.
Radial would be if, the letters/numbers pointed inwards toward the primer, and to read the case correctly you would have to roll it in a circle in your fingers.
There are, of course, variations, such as half-radial or arc, which is most commonly seen on American commercial.
Half of the headstamp is in an arc above the primer, half of it is in an arc below the primer, and both lines can be read when the case is held in one position.
I need to take some scans of these examples.
Anyway, unfortunatly, my long treatise on this case was lost, but it's definitely a Mauser type A case, the measurements point towards a 11.15x60R Mauser.
