Gentlemen
Thanks for your input.
First of all I checked Chorley and the loss of LN547 is very much included on page 327 ( I did not do that until now....

)

You say that Air Britain has this information. In my issue from 1991 it is not.
Seems you have a later printing of this booklet.
So can we settle once and for all that it was LN547 which was lost this late evening?
