Sorry that rather garbled Wiki comment about the modern Airplanes DAR company, is the only mention I've seen about a "DAR-13" (nothing at all about a "DAR-12").

i think that the thread must be renamed and instead 1945 to be to 1954 that's the year that the old DAR ceases to exist

ps. hesham sorry  for my late response
