Hello,
Same work as the Finnish one: plastic part of the screen replaced by a part of rodoïd with the good shape and the part below tinted with sepia ink mixed with "Klir"
I've a doubt and I need opinion/information. I've a doubt regarding the color of the underside of the cowling: RLM76, RLM04, both ? View attachment 712435
Steph, it's 76.
Check my post # 28 with 3 photos of the same a/c during different periods. The top one is from the time when Bulgaria changed the sides and the airplanes received white recognition markings. If you check the cowling it looks the same as in the earlier photos and doesn't show any signs of overpainting at all.
Cheers!
