I think that 2 (Typhoon) Sqn was busy forming at Lossie whilst 2 (Tornado) was still going at Marham
.
2 Squadron stood up as a Typhoon unit the day
after disbanding as a Tornado unit.
Then when the late decision to retain 3 GR4 Sqns was taken because of Op Shader, 2 (Tornado) had to become 12 Sqn, which had itself just disbanded at Lossie!
So,
after again.
Any examples of
before ??
