I've just had another look at the "Rudiments & Theory of Music" by the
Associated Board of the Royal Schools of Music.  Triplets are introduced
in Grade II (section 26 in my 1958 edition) and are shown without
brackets or slurs, just a number, when the quavers are beamed together.
Later in the same section crotchets are shown with a slur.  However when
explaining trills (Grade V, section 29a) the triplet on demisemiquavers
is shown with a slur as well as being beamed.

I suspect that this is either a US/UK issue, or else the use of brackets
is a more recent style, or possibly both!  Certainly 19thC music
published in the UK seems to favour slur-type triplets.
