The Antonov An-12 is a military transport aircraft originally built in the Soviet Union. It was used by many other air forces. The AN-12 is no longer produced in its home country, but the Chinese continue to develop new versions.
Wikipedia has more information about the original.
This item is basically an up-scaled version of my 1/1200 model. I have added cockpit and side windows, but no other detail has been added. I also have hollowed it out to make it less expensive to print.
