Good one Don. I have another '110 to do as a EpFr210 machine at sometime, working from info in John Vasco's 'Bombsights over England'.
Note that the old Microscale / Super Scale decal sheet is inaccurate - the EpGr 210 badge should not be enclosed in a shield at this date, just the red silhouette of the British Isles with the yellow sight over it. The shield came a year or so later.
I have yet to find accurate decals for this.
Also, it's very probable that this particular aircraft should be a 'D', with the boat tail (the one I'll be modelling) and the bomb rack beneath the fuselage, with the 'E' in the code being black outlined in white, not red, and WkNr. 3377, in white, on the port fuselage just forward of the tail planes.
EDIT: Note also that this unit was formed on 1st July 1940.
