I have weathered the model based on photos as an amalgam of typically worn airframes left outside, some panel touch-ups, APU exhaust staining, staining around auxiliary intake doors, and dirt where tarpaulin wraps are tied around the nose and cockpit in winter.
Modifications to the kit:
Corrected windscreen outline.
Cut out and scratch-built inboard flaps.
Corrected Kh-22 (AS-4 Kitchen) missile fins, spine, and warhead shape.
Added missing cut-outs between engine nozzles.
Added missing strike-camera window.
Scratch-built air intake trunking.
Closed auxiliary intake doors for engines off state.
Scratch-built cannon and corrected barbette.
Scratch-built missing avionics bay doors.
Opened up various air scoops.
Corrected undercarriage legs.
Corrected main undercarriage doors.
After-market items used:
- Neomega resin cockpit.
- Armory PE engine nozzles.
- ResKit resin wheels.
- Click to detail air-intake FOD screens
