Breastplate "Ready for air defense", a rare type

A rare sign in luxury condition. A twist in the selection. The manufacturer is the Vsekokhudozhnik artel. The rarity of the sign is due to the fact that only second-stage signs were made of copper alloys (as high-status ones), and rolled steel was provided for the first one. The only version for the first stage that is not made of steel. It is also notable for the use of black enamel on the left side of the sign. Guarantee of authenticity.
