FWIW I'm from the UK and was taught this notation in high school history classes (though the C encircled the 19 when hand-written). That said I had trouble parsing the "C19" too so I don't think I've seen it used in print much. I tried to read it as a UK postcode zone first :) (I used to live in SW19) |
