A very nice badge here, awarded to commemorate service by Dnieper River Naval Flotilla veterans. Quite complicated and well made for a commemorative badge. Hot glass enamel. Working pin and catch to the reverse. 
 
The Dnieper Flotilla (Russian: Днепровская военная флотилия, Ukrainian: Дніпровська військова флотилія) is the name given to the various naval flotillas on the Dnieper River. These were particularly active in four conflicts: the Russo-Turkish wars of 1735–39 and 1787–92, the Russian Civil War, and World War II
