A very nice looking Hungarian MHSZ "Homeland Defense" badge here, working pin and catch on the reverse. Enamel shows some light wear/dirt but is in good condition overall. Produced between 1968-1990. Badge displays well. 
 
The Hungarian National Defense Association (MHSZ) was a national paramilitary organization organizing sports and leisure activities between 1948 and 1990. During its history, it was transformed several times for political reasons.
