and it is 5-4-0, it is not fiveforty, or fivehundred forty
them CW types are touchy about stuff like that
Wandering off topic a bit again but, that's not always true 216 Sqn is pronounced as two-sixteen, it's to do with their previous history and transfer over from the RNAS where they were 16 squadron. When the RAF formed the RNAS air units were mostly given numbers in the 200 range, up to about 225 were all directly created from RN units iirc. The units that were XX squadron RNAS became 2XX squadron RAF. Totally irrelevant I know, but I got some bad looks when I turned up there calling it 2-1-6
Nos 1-200 are RAF or RFC squadrons. Up to about 150 Sqn are the former RFC sqns with the rest being RAF squadrons formed sometime after April 1918.
Nos 201-225 were formerly RNAS squadrons renumbered straight into the 200 range. Up to 274 Sqn are former RNAS units formed by combining various flights up to squadron strength.
Nos 274+ are wartime created squadrons.
Nos 300-352 are squadrons formed from personnel escaping occupied Europe.
Nos in the 400 series are Commonwealth squadrons placed under control of the RAF.
Nos on the 500 series are mostly wartime created units, many of these are special operations types (RCM, recce)
Nos 600-616 are RAuxAF squadrons.
Nos 617+ are wartime formed squadrons.
you got some odd ones in there two, offhand IIRC thought it was IX and XV
