Of the 'others' that I've no photo's of, I would draw your attention to 210241, the next a/c to the JV44 "Red 13" - likely it would sport a VERY similiar camoflage. For me tho, my 'to do' list includes all 5 JV44 Dora's - thus 210240 "Red 13" will be done and 210982 "White 13" from 1./JG26, because it just looks 'right'. Those are the only "13's" I have any intent of doing.
The next Dora however, will probably be either 601088 "Black <1+~" (in its PROPER camo, not the modern day museum camo) in the form on Tamiya D-9 + Verlinden and etc or more likely an Eduard D-11 220017 "White <<-".
