I play Letham Grange at least once a year.
Donald Steel ? ...... well the story I was told, is it was designed by the original owner, but he was so unsure about how to build greens that he called in Donald Steel to do them.
So its an amateur routing with Steel greens ?
(Did Jim Finnegan not cover this in his book ?)
IMO, it was a far better course when it first opened, but there was problems with a house sitting on the right hand side of the 18th and too many golfers "going for it", that it had to be re-routed.
Three of the original holes were lost and were replaced by three poor holes IMO.
I remember playing it on the year it opened, with persimmons etc., and it seemed to be the longest, hardest slog of a course I had ever played, and came off the course with loads of blisters on my feet.
The 2nd time we played it, be used "buggies" which was another first for me !
Course has always struggled to remain open, with location being blamed a lot of the time.
