Aw man, you’ve ruined my weekend!
Seriously, those are rare and beautiful models. Look after them, they’re in amazing condition too. These Aviaexport airliners are getting harder to find these days. That Tu134 is rarer than the more common and longer Tu134A models. The Balkan is very rare indeed. I used to own a 1/50 LOT Tu134 in the old delivery colours.
