Re: WG466 and WG486 - I think overall LAG was normal for all the Chipmunks of the Gatow Station Flight, as WP850 and WZ862 also appeared in this scheme. WG478 was the exception, there in May/June 1987 and again April/May 1994, but it was only intended as a "reserve" aircraft.
I'm a little confused by the description of how Slingsby were told to do the overall LAG (maybe I shouldn't be) as this was previously well described in DH's Mod H.293 dated 24.6.1970.
