Hi ...Yes . Definately a BBC production....I expect quite a lot of us would like a copy ( me included ) for nostalgia sake.
I wonder if Major Laraby (Mathew ) could help us out with some details of filming ?
As an asside , "Wings" was the instigator for Leisure Sport 's (Thorp Park ) director John Hall to start up the WW1 theme with purchase of DrI , and then all the rest.
BTW.(only slightly off topic )..Did anyone ever see " The Flambards" ? ,,Worth getting too I'd think .

...Regards JM
