Thank You very much! I certainly am going to try keep it going.
It is Yak-42D.
Ok, I just wasn't sure, as I saw several some photographs titled "Yak-42D" and they showed no hump, so I got uncertain if it's error in naming the photos or the hump hides some
optional equipment.
A suggestion, if you don't mind: I'd
translate the organization name as it's not commonly known and is not easy to read anyway
But I'm not translating the organization names
deliberately.
Check my drawings either in these threads or my threads about Polish and East German aviation - only exceptions (first partially accidental, second because I wasn't sure of the original name) are Po-2 in Polish Wings and Estonian Airco DH.9 in FD Scale Aircraft 3.
Actually I was tempted to write a full formal name of that ministry instead of that shorter, common one...
