You could try Goresbridge but don't know whether they would give out purchaser details. They don't publish their old catalogues online that I'm aware of. For what reason do you want the old catalogue? PM me if you prefer as I may know a way of getting the page for your mare.
Your horse also went through the Goresbridge sales in March 2007 where she was sold for 600euros to J. Phelan.
In Grace's View also ran a few times in p2p's finishing 4th twice but was beaten a long way. (Source: www.p2p.ie)
You could try contacting Weatherbys who have an extensive database. Try their website www.weatherbys.co.uk for contact details. Think it's bloodstock department you need.
ETA: £1200 is a bit of a bargain basement yearling! Have you seen her page when she went through the sales ring...
