West Herts
Bingley St Ives

Thanks for your considered input - as you say the definition of an OD v a redesign is important. I feel that if there is an existing routing and the large majority that's reused it's more of a redesign.
As per your list of courses
Western-Super-Mare: didn’t Dunn do the original course and AM redesign some holes?
Broadway: I couldn’t find evidence per Neil Crafter’s chronology?
Malvern [The Worcestershire]: noted - the club moved to a new location with an AM design [will update]
Walsall: as per above
Stanmore: wasn’t this a redesign by AM?
Halifax: wasn’t this a redesign by AM?
Nelson: didn’t it have an original 9 by Lowe and AM added a further 9?
South Moor: didn’t Fernie do the original course and AM do a redesign?
Crosslands Heath: I couldn’t find evidence per Neil Crafter’s chronology?
Blairgowrie: didn’t Mackenzie extend the original 9 holes to 18?
Grange-over-Sands: according to Neil Crafter’s chronology there’s some evidence but it’s not definitive?
West Herts: didn’t Morris do the original course and AM do a redesign?
Bingley St Ives: as per others here - I believe this is a CA Mackenzie design
Headingly: noted - the club moved to a new location with an AM design [will update]
Harrogate: as per Neil Crafter’s chronology wasn’t AM involvement more of a redesign?
Pollok: didn’t someone else do the original course and AM do a redesign?
Seaton Carew = didn’t McCuaig do the original course and AM do a redesign?
Muskerry = didn’t McNamara do the original 9 and AM extend it to 18?
Rhayader (NLE) = noted – 1908 to 1968
