This Ilyushin Il-14 airliner appears to be ex-air force, but Ceskoslovenske Aerolinie (Czech Airlines, or CSA), were the primary users in Czechoslovakia. The Il-14 was one of a series of improved DC-3 and DC-4 copies developed in Russia during the 1950's, and many survived into the 1980's. Today, while they no longer work for Aeroflot or CSA, they are used by smaller airlines and charter services, especially in Africa, as they can land safely on dirt runways. This applies mostly to 4-engine Il-18's, though, rather than 2-engine Il-14's (the Il-18 was more than simply a DC-4 copy, however, and was by far the most advanced of the series).

This is not unlike the fate of the surviving Douglas DC-3's. As historians will note, Ilyushin were not the first Soviet design bureau to copy the DC-3, as the Lisunov Li-2 was an even closer copy produced during World War II. The Kbely museum actually has one that they keep in one of their hangars with other World War II aircraft.
