Muzzle Velocity edit
The Article currently says:
The muzzle velocity was 490 m/s, which was low compared to the rifle-calibre machine guns of the period such as the German MG 08, but a respectable performance compared to other automatic cannon of the period, such as the Vickers QF 1 pounder pom-pom.
But the article for the pom-pom states its muzzle velocity as 550 m/s. Sounds conflicting to me. --BjKa (talk) 08:04, 3 September 2014 (UTC)
Origin of the weapon (and the Oerlikon 20mm which followed) edit
The Wikipedia articles cite Dr Reinhold Becker as the developer of the weapon. However, various sources mention the Conder brothers as the original developers, with the patent filed by Becker's company. The 20mm weapon was originally based on the 19mm cartridge. Dates vary from 1913 to 1916.
The above web articles in turn refer to an article by Ian V. Hogg ([4]). Hogg was an authority on firearms, so this entry (and the entry on the Oerlikon 20m) might need some changes in the history section.

As I have no access to this article, and I am very new at editing, I have left this info for more experienced and knowledgeable editors to develop into the text. However, I have made a small edit in the main article owing to the need for accuracy in the history of this important weapon system.
NOTE: There is no English Wiki entry on Reinhold Becker, who seems to have been a notable industrialist and philanthropist. The German Wiki entry is: https://www.wikiwand.com/de/Reinhold_Becker
Can the German entry be cited in reference? Should an English Language version be made (Translate the German??) ?
There's also no entry on the original company that developed this weapon.
I was unable to find any information regarding the "Conder brothers" on the web.
Someone who understands German might have more luck...
