"Grey Nurse" was 457 sqns name.
It was carried by at least 5 different Spit VIII's with sharkmouths.
ZP*Y ended up with 4 eyes when the new sharkmouth and eyes (3 different versions) were applied and the old eyes left on.
RG*V (my one) only had 2 eyes. Flown by Robert "Bobby" Gibbs, hence the RG code.
Other ones I know of
ZP*Q
ZP*W
ZP*X
Hope this clears things up.
