Some were, some weren't...no one was immune to redesign.
The difference, Willie Park II created inland designs that emulated the natural qualities of links golf, and he spent time and great effort developing these courses...as opposed to the fomulaic cop designs, usually on a flattish field somewhere and normally laid out in a single afternoon.
There is a good reason Old Tom got no respect as a course maker from the likes of Garden Smith, Horace Hutchinson, Bernard Darwin, etc....even though they loved him personally.
