It's interesting that Tom Dunn's design style is described as crude and basic by Simpson and Huchinson. If you look at Dunn's resume, it's impressive, with credits at: Broadstone, Worlington, Woking, Lindrick, Seacroft,Ganton.
But all of these courses have major redesign credits by much more respected architects such as Colt, Campbell... I still wonder however, if Dunn deserves some credit for basic routing of some of these courses?
We obviously know that Woking was transformed by Low and Patton, but is the routing Dunn's? And Broadstone was redesigned too, by Colt (although Darwin clearly liked two thirds of the holes there before Colt was involved). Ganton has evolved through many different architects and I have no idea what remains of Dunn's work. And I have no idea for Seacroft or Lindrick.
The most intriguing is Royal Worlington and Newmarket. That course is the polar opposite of Dunn's apparently crude style. Colt did redesign all 9 holes but I remember that we had an extract of the club's history posted on this DG some time ago by Dan Robson and it wasn't clear how much Colt had changed the holes. (Maybe Dunn designed one great course?)
