TB Pedigree-Anne Gribbons 1st Dressage GP horse
If that isn't a classic TB sport horse pedigree, I don't know what is. Very tightly linebred to Phalaris/Scapa Flow with a line to Pharos top and bottom and a line to his full brother on the bottom.
And Gainsborough top and bottom also.
Okay, so he was a long time ago, but he still made it to GP with his breeding. :)
Found out about him in her Between Rounds this week, which is well worth reading.
