Leigh,
Just to add with this topic, I am not sure what the observable
is but I know that gravity waves is a predicted result. You might to
look up the LIGO experiment and search gravity waves on a search engine.
For LIGO, it is under Non-accelerator experiments at SLAC's experiment
list: http://www-spires.slac.stanford.edu/FIND/explist.html.
As far as Levi-Civitia and Robertson, the work may have been
publish in Physical Review (one volume that long ago) or a popular
European journal of the time. It sounds as if they may have been
European, so maybe people can help me here but looking up Il Nuovo
Cimento or a German Journal (was Zeitschrist fur Physik that old?). If
they were English, then Nature or Philosophy of ??(something - Nature?)
is also a good bet.
Good Luck.
Sam Held

I can't help out on the history, or on the GR for that matter.
It is the case that the Kepler problem has not been "solved"
in GR in the closed-form sense that it has been solved in the
Newtonian system. A solution in numerical (or perturbative)
sense has been achieved, however, and an supporting example
exists in observational astronomy, the binary pulsar
PSR 1913+16, and a web search on that designation just yielded
140 hits, so there's lots of information out there.
