Just thought id let everyone on BOCN know out of interest there is a free downloads website called scribd.com where you can download PDF files, army manuals and books on artillery, cannon and mortar ammunition inc technical diagrams and data on fuzes etc. Ive allready downloaded two complete manuals of around 50 to 100 highly detailed pages and the pictures and info are just amazing and its free! Dont know if many know about this website so go and have a look. Just sign up and then put what you are after into the search category and watch in amazement, the choice of material is superb.
