One of the best builds I have ever seen...
Wow, what a great homage, and from a very experienced modeler, THANK you very much!
could be instructions to pilot (turn left, dive or turn right). That way the gunner could have a better field of fire/evade attacker?
Thank you Juan! You have not seen the model together, but this is not possible, because only the pilot can reach the board on the upper wing. The gunner is to much aft.
What was the use of that weird tool with the icons you are asking about those left side fields?
Andonio, the left side are symbols for own aircrafts (cockade), a unknown aircraft ("?") and germans (with the cross). So the pilot can tip to the cross and then the direction to tell the gunner: "See, there is a german"
A friend come up with the idea, that the colors are related to arming (red to cock the guns for example or white to secure) or may be related to bomb release.
Cheers,
Frank
