The 4,3 & 2 strands are what was coming out of the ceiling - the light
fitting is wired fine as you would expect. The problem is trying to
match up this 'old' wiring configuration with a modern light
fitting.....it looks like Alan may have established what the problem is
though.

Without disturbing any of the other essential wires, you should have made a
sketch and then just re-used the three conns that the original (working)
lamp had been connected to.
It was an upgrade swap.
The reds are typically: 3 continuous line all junctioned and 1 switched line
from wall switch.
