According to www.praktica-collector.de, made in 25245 ex. between december 1965 and january 1969. Historic interest: the first Praktica with light metering through the pentaprism. Fabric shutter curtain. In good state, only lacks a cover on the cocking lever. The separate light metering by the large round button in depth of field tester position was taken over by the Russians on Zenit 16 and 19.
