I don't think I have any articles discussing the formation of Hawrtee & Taylor. It is inetesting that it is H & T and not T & H.
In a 1925 advertsement they listed these designs/redesigns, in order: Richmond Park 'Princes' and 'Duke' courses, Highwood (Bexhill), Chigwell, Rochford Hundred, Boyce Hill (Benfleet), Hull, Swinton Park (Manchester), Birmingham Municipal, Knowle (Bristol), Herne Bay, Bognor, Denham, Sonning, St.Leonards-on-Sea Hastings, West Middlesex, Royal Musselburgh, Williamwood (Glasgow), Littlehampton, Mid-Surrey Ladies, Chiselhurst, All-Weather Golf Practice (Kennsighton), Royal Porthcawl.
Didn't Colt redesign QP Bournemouth in the 1920s? I recall Paul T posting an article on that a few years back.
