I dropped by for a look at how the indexing was going in your topic as probably the best barometer there is for what's happening. As you say it's rebuilt the posts with images to over a year ago so yours (as a 4.5 year long topic) has gone back about 18 months now so hopefully it'll have done yours within 2-3 days. With the current site, as a whole, being 9.5 years old I'd estimate the indexing is likely to take over a week - and that's if it gets to looking at old topics that are rarely visited. Considering it had only managed to find four topics with the word Hornby in them in the first day (whilst offline) then it's definite progress.
