HP Folland himself was a fighter aircraft designer going back to such as the SE5, Grebe, Gauntlet, Gladiator etc. He resigned from his company in 1954.
Bill Petter ( ex - Westland) was then the main instigator of the Midge/Gnat ( after such as the Lysander, Whirlwind , Canberra and P.1)
Being of a religious persuasion he wanted the Midge blessed. As this wouldn't all fit in the church only the fuselage had water sprinkled over it. Probably the rear fuselage (hobson units etc.) was missed. Pity that.
