Papa,
I found this a couple of days ago. Hope it helps.
How is the quality of the parts? I stopped building Revell aircaft kits because of the bad quality compared to Hasegawa, Academy, Italeri.

btw if you want to apply rusty parts, I recommend drybrushing with Humbrol 29. It's a great rust color imo.
Any way, good luck and happy modelling!
