Do the horns work if you ground the wire that goes to the steering column? 
The Tiger shop manual (online at tigersunited.com) has a really good cross section view of how the steering column and hub parts go together. I would also look at if the horn ring wiper is making contact to the ring that mounts on the steering shaft.

Theo,
Yes, the horn ring provides a ground to the horns.  Grounding the wire that
goes to the steering column should make the horn blow.  In their infinite
wisdom, Rootes connected one side of the horn(s) to the + side of the
battery, forgoing the requirement for a horn relay.  When the horn ring
grounds the other side of the horn, current flows through the horn and it
blows.  The problem with this scheme is that full horn current flows
through the horn ring and the ring may become pitted from arcing.  If you
are doing some work on your horn circuit you might want to install a
conventional horn relay so the horn ring only has to pass the
relay-energizing current instead of the full horn current.

My horn was never reliable from birth and I was never able to adjust it so
I could rely on it,  Disassembling the horn ring assembly showed that the
ring was pitted in many places, and cleaning it did little good.  I have
recently installed a horn relay and it now works reliably.
