OP As far as I can see, the red wire does run from the transformer to
the ringer, and both ends of the red wire are unused and wrapped around
the brown cable. I suspect that I would connect it to the FRONT (door)
terminal in the ringer, and in series to one or the other wires at the
transformer. I'll pick up a cheap ringer in the next few days and try
it, and let you know how it works.

Here's a couple of links to some sites about doorbell wiring (watch
for wrap):
