Anorak on:
There are other odd ones too as not every number has been allocated. I believe 188 is the lowest number not to have been allocated but it did feature in a film - can't remember which one.
The very newest sqn was 360 as it had never been formed during the war and 361 was also allocated at the same time but not formed. It might also be said that 360 was the first training sqn with a number as it had no operational war role in its peacetime guise. It was earmarked for airborne relay so, in that role, it might have claimed operational status.
