My Great Grandfather was D. E. Walker. When my brother, Gary, was a CA Fish & Game Warden in Alpine County, CA, he found a Visalia saddle and purchased it. We have no idea the history of the saddle but would be interested in any information you may be able to provide. There is a mark near the pummel (TRADE D. E. Walker Maker Visalia, CA MARK) and a serial number on the back of the saddle (Visalia Stock Saddle Company - AB364 30 - San Francisco, CA) I have photos.
