I'd been waiting and following the board policy of not commenting on a live ebay items, but it is closed now.
Its very hard to tell if a piece of Galle is right from an ebay ad. I however will agree completely with Frank that this one does not look promising, based on its pictures and description. (the base particularly looks wrong and as Frank says the quality looks poor)
To be fair though, on Ebay(dot)com there are a number of high priced and almost certainly right Galle pieces - there is even at least one on .co.uk that looks very promising (again not cheap). I suspect if you followed particular US dealers and checked their feedbacks over time you could at, a highish price, buy a great Galle from ebay(dot)com without a lot of real Galle expertise. Making it possibly a much more reliable method than buying some of the pieces of so called Galle that have been offered and sold (at high prices) in recent provincial UK auctions!
cheers
