Wonderful Bradley and a brilliant find, these are all early Mackenzie courses and date before the start of WW1, so pre 1914. Fortunately some of these were included in his 'Golf Architecture' book from 1920, while others were not and are certainly ones I have not seen before. I'll try and put titles to the ones I know at least, captions in quotes are from his book. Good comments from Paul and Mark.
Your first photo - I'm not sure
Your second photo - "A bunker on the Fulford Course, artificially constructed on flat land at a cost of 5 pounds."
Your third photo - "The Eighth green at Moortown: 170 yards, entirely artificial" the famous Gibraltar hole
Your fourth photo - not sure, certainly looks like Mackenzie at the front of the green with his putter.
Your fifth photo - Moortown's Gibraltar repeated.
Your sixth photo - same one with Mackenzie repeated
Your seventh photo - "Artificial hummock at Moortown, constructed from the stones removed from the fairway." Not sure what hole.
Your eighth photo - just a guess, could be Headingley I think.
Your ninth photo - "The artificial hummocks guarding the fifth green at Alwoodley: approximate cost 8 pounds"
Your tenth photo - think this is Moortown
Your eleventh photo - "The sixteenth hole at Headingley, Leeds, approximate cost 50 pounds: an entirely artificial hole, the site was originally on a severe downhill slope and had to be cut out of rock."
Your twelfth photo - certainly Moortown, not certain which hole, could be Mackenzie at the right.
Your thirteenth photo - "The 140 yard short hole at Sitwell Park: a fiercely criticised green that has become universally popular"
Your fourteenth photo - "The fifth hole at Fulford, Yorks - approximate cost 35 pounds: the whole of the additional nine holes on this course were reconstructed on dead flat land at a total cost of about 300 pounds"
Your fifteenth photo - not sure about this one, possibly Moortown or Alwoodley?
Anyway, a marvellous collection Bradley. One thing that is immediately noticeable - his work at Moortown, especially the 8th stands apart from the others in terms of its naturalism and a foretaste of things to come. The others appear somewhat crude and cartoonish by comparison. His post WW1 work reveals a maturity and a confidence not readily apparent in his pre war work.
Certainly some further investigations needed to pin down the holes/courses of the ones that were not published in his book.
