IAF A-4E 819 build has been shelved. Instead will build this model when they were in late Indonesian service. I have found better pictures of these A-4Es. Notice under the nose what looks like a radar altimeter in top picture and on the right side offset is a large blade antenna in bottom picture.
Luckily have the FCM decal sheet and very advanced on the build. Will just have to scratch build the blade antenna, a few other sensors, and the radar altimeter.
