1st variation - medallion and suspension are made of German silver; plane is made of tombac and gilt, attached to the medallion with two rivets; serial number is hand engraved; raised MMD mint mark. Screwplate is made of German silver with raised "Monetniy Dvor" mintmark. This badge was established in 1965, when other badges in this group were no longer made of precious metals, so I am assuming that this is the first variation. At this moment I don't have any reliable information about later variations. Total number of awards is unknown.
Total weight without the screwplate - 18.0 grams
Weight of the medallion - 9.2 grams
Screwplate - weighs 2.2 grams, measures 16mm in diameter
Suspension measures 24.5mm x 16mm
Medallion measures 27.5mm x 23.0mm (without the loop and the extended piece of metal with "CCCP")
