Fieldcrest, sold by Bedford Tack, is another one that is still currently made (in England.) They are good deal if you can find a used one.
"theotherseat.com" sells a suede seat cover that can be used on any cutback. If you have a wide flap saddle, just make sure that she knows that, because the understrap has to be set back about 2" to accommodate a wide flap.
Whitman was run by the Norman family. The factory is in Kalamazoo. They sold their business to EEG in 2000 or so. EEG went bankrupt and the Norman family bought back the factory and made the "Norman" saddles for a while. I'm not sure whether or not they are out of business or not. They lost the Whitman / Coventry / Campbell brand names, and I think Weatherbeeta may own those. So they came back as the Norman saddle.
