Audio of Lancaster Under nightfighter attack

I dont think there's any doubt that Wynford Vaughan Thomas and a
BBC sound engineer did indeed fly that mission on an RAF
Lancaster, nor do I doubt that they did indeed record on that mission.

However its not impossible that AFTER the mission some dubbing
occurred to increase the audibility.

That sets me thinking about what audio tailoring the BBC had in those
days. Even some wireless sets had the usual top cut or bass boost
controls. I will ask on a B/C newsgroup and report back. There may be
some oldies around.
