MS. History of Winchester School

"In the year 1715, proposals were published for an exact account of the History and Antiquities of this College of St. Mary; and large collections are made for that end, now dormant in a private hand."—Rawlinson's *English Topographer*, p 63., London, 1720. Can any of your readers tell me where this invaluable MS. (if existing) may be found? and also what became of the late Rev. Peter Hall's collections in manuscript?
