Information for article on High-low System

The Germans developed the high-low propulsion system in desperation. The following pages are from German Secret Weapons of the Second World War by Ian V. Hogg printed by Greenhill Books/1999. Page 168; Page 169; Page 171; Drawings of ammunition for WW2 German high-low cannons; and Photos of captured high-low cannons. In addition page 458 from Jane's Infantry Weapons 1976, one of the first to explain the operation and details of the 40mm high-low propulsion system. I also have three photos on the sandbox user page for the article. --Jackehammond (talk) 08:36, 8 February 2010 (UTC)
