Apparently, Richard Castelow was a former master saddler to HRH Queen Elizabeth II in the UK and now resides here in Wellington, FL. His saddles are very well made, and this one is no exception. It has a 17.5ins seat and a medium width fitting, but no stamp marks can be found on the saddle, so it is virtually impossible to find out much more information on it. The saddle flaps are long – ie: 18ins, so built for a tall rider. Most of Richard’s saddles are custom made. I measured the gullet to be 4.5ins (approx).
