That brings back memories. I have that exact book sitting on my gun book shelf. It's actually pretty good but nowadays with the interweb, you don't really need it anymore.
Actually a few interesting books at that link, the Canadian Lee Enfield ones seem to be popular in Italy, seen sites there hosting them before. Still some oddball books for sure.
