Well done Nick as it retailed for 25. Most in depth work you will find; you will not be dissapointed. The author worked for the Royal Armouries so had access to a lot of stuff. Another to look for is 'Drawing Fire' by Private Len Smith. He was a First world War sniper and accomplished artist. His job being to get close to the enemy lines and produce accurate drawing of their defences. He made such a detailed drawing of a blasted tree trunk that they were able to make a replica and then go out at night and replace the original so as to use it as an observation post. All hairy stuff. I collect objects etc. connected with Great War sniping. Interesting subject. Lagopus.....
