I have recently purchased a copy of map (Sheet II) used for defining the northeastern boundary of British India and Tibet on March 24, 1914, on eBay. This boundary is commonly known as the McMahon line. I found a low-resolution copy of both maps on Wikimedia (https://upload.wikimedia.org/wikipedia/commons/6/62/McMahon_Line_Simla_Accord_Treaty_1914_Map1.jpg https://upload.wikimedia.org/wikipedia/commons/7/79/McMahon_Line_Simla_Accord_Treaty_1914_Map2.jpg). It seems the map I purchased was taken from a book. I contacted the seller for the book name, but he does not remember the name. Has anyone seen these maps in a book? The maps used for defining the boundary were published by the Survey of India on August 1913 and the scale of the maps is 1 inch to 8 miles, the names of the sheet are: North East Frontier Sheet I and Sheet II. Does anyone have these maps in your collection? If you do, would you mind sharing a digital copy with me?
