Breath taking prices shown for those books, in those links!!! I did get one of them in August 2019. A bookstore in Australiaicon as a seller on eBay - was $C 99.50 mailed to me. Information quite consistent, generally, with "Pattern 1914 and U.S. Model of 1917 Rifles" by Charles Stratton. I tend to use the Stratton book more often. It was $C 33.52 mailed to me from Amazon.ca in Feb. 2019 - probably stupid nuts higher price now, I suppose...
