You could also do it with a pocket query. You dont even need to "officially" run it.
Set one up without picking a day to run, center your co-ordinates in town or w/e. Pick a radius that is appropriate for your region, and set the placed date from Jan 1999-Jan 2002, then preview the results, if there are no matches, expand your date somewhat and preview again, eventually if you can get around 5-10 hits, it should be fairly easy to see which is the oldest of the lot.
Edit, I ran one for you, see if you can open my search results
And it would seem that tugman and wifey are correct with GC30FF
