Description: Illustration of a Hinged Counterweight Trebuchet Prepped for Transit from the Wujing Zongyao, late Ming (Wanli Period) edition. The photographs are part of my book. You're welcome to use them on Wikipedia so long as you list my book "Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity" by Liang Jieming (ISBN 981-05-5380-3) as the source. I hope that helps. Cheers, Leong Kit Meng (Liang Jieming) <liang_jieming@history-forum.com>
