Here is a long shot....
Back in 2017 we visited Nis-Konstantin Veliki Airbase to catch our flight back home.
From the civil side we noted some stored Gazelles, a An-2 and two J-1 Jastrebs.
Stored near military apron:
70371 An-2TD (T-71) nn Serbian AF without engine
12651 SA.341H (HO-42) nn Serbian AF rotorless VIP c/s
12755 SA.341H (HS-42) nn Serbian AF rotorless camo c/s
12824 SA.341H (HN-42M) nn Serbian AF rotorless
1x SA.341/SA.342 nn Serbian AF rotorless
2. . . . J-1 (J-21) nn Yugoslav AF broken up camo c/s
2. . . . J-1 (J-21) nn Yugoslav AF broken up yellow c/s
We were able to identify the An-2 and three Gazelles. But we are still looking for the serials of the fourth Gazelle and the two Jastrebs.
I added two photos to give you all an impression.
If there is anyone who can help on these, any info is more than welcome.
Best regards Rob.
