Belgian Velo-Dog Revolver - 5.75mm Velo-Dog
The Velo-Dog was a pocket revolver originally created in France by Charles-François Galand in the late 19th century as a defense for cyclists against dog attacks. The name is a portmanteau of "velocipede" and "dog". Velo-Dog revolvers were manufactured in France, Belgium, Spain, Russia and other countries in numerous versions, often with folding triggers. While the original version used specially designed 5.75mm cartgidge, other models used .22 LR, .25 ACP and some other cartridges.
