WW2 Polish 1WDP Lenino-Berlin (1st Regt) badge With screw back fixing.
A Polish People’s Army unit that fought on the Eastern Front from Lenino in 1943 through to the Battle of Berlin in 1945, this is an official Polish veterans’ badge issued by the state after World War II; it is not a wartime item or a reproduction, but an authentic post-war, government-minted commemorative badge.
