That's the auction number all right!! 270535037606, recorded in the database on 21 Feb, 2010.
Unfortunately the DB doesn't list the buyer, so I can't verify that katygb is the same person as jebboats, but it's not unusual for ebay members to have more than one registered name. A lot of flippers do. One for selling and one for buying.
We know jebboats is out of Dothan, AL, but I don't know how to find out where katygb is out of. Anyone?
