Three fictional Belgian camel skins for your consideration.
First, my personal skin, featuring J2_style tailfin in Belgian colours and personal insignia. The planes bought by Belgian crown from UK were supposed to be brand new ones, so it's hard to explain where badly scrubbed-off English inscription came from...
... (yes I know it's anachronism).
Second, personal skin of J2_Bidu. Same basic plane, Japanese caligraphy fuselage emblem.
Finally, a generic Belgian plane for J2 pilots. No identifying markings.
