I was trying to find a way to do this myself earlier this year, but unless its a real serious problem (in which case I believe ebay can get the info from their archives once you contact them), there isnt a way of getting the listing details from them. Its worth trying a direct link to the page if you have one though. It didnt work in my own case, but the one teresat posted here works, and sometimes you can get them to show on Google as well
