I knew a Fugly...16.3ish chestnut tb, ex racehorse, was in Devon about 4/5 years ago aged about 16 I think. Also known as Steve. I rode him a bit for some people, I have a pic somewhere if it sounds like the same horse. Sadly this Fugs was PTS in 2004 due to arthritis, he had let us know that his bad days were occurring more than the good ones and he was becoming awfully stiff. Let me know if it sounds like the horse you are looking for,
I'm afraid I only knew of a Fugly about a year or two ago. He was given to a friend of mine but she couldn't afford to keep two so after a while she sold him - That was in the Herts/Beds area.
He was bay with a slightly roman nose, he could be a little cold backed but was fine if managed correctly and he was a full TB- his proper name was Coming Thru' and he was by Bustino.
I forgot- i bought him from Beds! The yard was on a really steep hill.
