Hello gents,
From what I found out, the paper model from Schreiber Bogen (Germany) appears to be a nice and simple vintage model of 1/50 scale, out of production for many years.
And here is a colored side view of '56-6722' with a red stripe with well-known animal.
By the way according to my little one this is a 'black squirrel'
The next painting scheme could be a black one of the same '56-7622' airplane.
Later on maybe a 'silver one' could follow. However, that would need some tests with printing on 'metallic' cardboard and homemade decals from what I can see now.
I hope you are all OK and if you stay at home because of coronavirus self-quarantine you have some time for your beloved hobby!
