A pleasure Mr Expert!
Can you imagine the spectacle at an airshow if things had been different...?
"And now ladies and gentlemen, running in from the left, the Battle of Britain Memorial Flight Lancaster, Spitfire(s) and Hurricane(s)...
"...followed by Charles Church's Lancaster, Spitfire(s) and Hurricane...
"...and last but by no means least, Doug Arnold's Lancaster, Spitfire(s) and Hurricane..."
The airframes all existed... and still do, but rather more scattered.
