Looking for 4 y/o breeding stock horse

I owned a horse about 3 1/2 years ago and I am looking for him. His name when I had him was Quinn. He is a Thoroughbred/Paint Cross, but is a breeding stock chestnut with an upside down arrow head on his forehead. He turned four in March. I have pictures of him when he was about six months old, more for reference on his markings, as his facial markings are pretty unique. Any information would be appreciated. I am more than motivated in getting this horse back. Everyone has that one horse that you can never get off your mind and would do anything to get back. He is very loved.
