I have a King Ranch Saddle/ Charles Day saddlery, custom in 1975. Im interested in selling it but do not know the value. Charles Day Saddlery leather stamp is sewn on the rear of the Saddle, and the brush guards are stamped King Ranch.Some pictures follow. Thank youhttps://photos.app.goo.gl/qayVUYP5FLeoJv4T8
