What genius dreamed up the British ones - he'd obviously never tried to sort them on a computer:

1 or 2 letters followed by 1 or 2 digits then a space then 1 digit then 2 letters. So after B1 comes B10, B11 etc, and B2 doesn't get a look in till after B19.

And then central London is different again - not EC42 but EC4P!!

But then the GPO persevered with odd 1/2ps in stamp values long after everyone else had given up.

Confused? You will be.

WassaiL! V
