Although there are 20 mph discs painted on the road surface, there don't
seem to be any signs on posts marking the start or end of the restricted
area. Presumably there isn't actually a traffic order for the 20mpgh
limit,
and it's basically a hoax.... so what's going on here, and why?

as you say it's an attempt to slow the traffic down with no legal force.

There' a similar situation on the A30 outside hook, a 70mph Dual
Carriageway with slow signs before a vunerable junction, without
a nseparate speed limit sign they have no legal force.

These are pretty common - the "slow" sign on the road isn't so much a sneaky
way of reducing the speed limit, it's simply a warning of a hazard; much the
same as chevron boards on bends. The fact that it sounds like an instruction
probably helps to make the hard-of-thinking actually take notice.
