Hello Smilo,
OK! Thanks for your interest.
Meanwhile I also found a series of pictures of two g4e specimens with a cockpit gun recovered from a Norwegian lake in 1986 and beautifully restored in a Museum in Norway and in Wunstorf, Germany.
Detailed photos with better perspective show a centred cockpit machine-gun ring position, so I can correct that. Also, more or less, what I have in yellow for the g3e bomber that served in Crete and Greece, can be black for this version, and the green can be a greyish black, so there can be two liveries of the armed version.
Cheers,
Aleatorylamp
