The Bradac brothers or bratri Bradacove started making cameras in the 1930's. They had a factory in Hovorcovice, Czechoslowakia. Their Kamarad TLR cameras are the first in what was to become the Flexaret TLR series, made by Optikotechna and later Meopta. Financial difficulty forced them to close down their factory. Optikotechna in Prerov then employed both and continued their camera line. In 1946 this company was nationalized and renamed Meopta.
