A very nice pre 1956 Hungarian MHK badge complete with textbook Rakosi era "S style" pin on the reverse. The MHK was the Hungarian equivalent to the Soviet  "Ready for Labour and Defense" athletic program. The name of the organization is "Munkára, harcra kész" which translates directly to "Ready to work, to fight." MHK existed from 1949 to the mid 1960's.
