Offer horse as a sideman

Offer horse as a sideman - I am looking for a nice home for my 23 year old gelding as a final home. He is sweet and well compatible with other horses. After consultation with the vet, only conditionally rideable. Or a loving retired life. He had an arthritis finding in the right fetlock head in 2018. I have had no problems with it in our 3 years together. He is currently healing an injury in the fetlock beam. He has been sprained while out on a trail ride. Hence my decision not to ride him anymore. The decision to sell has been on the table for some time, as I can no longer do him justice for private reasons.
