Hi - yes Karsh was an Olympic team member. CSHA, FEI and performance registered. He showed hunter and jumper and did puissance up to 7.1. He was owned by Molly and Fraser Wright. I am currently breeding my mare to him by AI -frozen. He was a 16.2 grey. He was reported to be of excellent temperment and ridability. If you would like to check the EMG bulletin board page 6 of the breeding section there is a write up about him found in an old CSA article.
If you would like contact info for former owner you can contact me at firstname.lastname@example.org
