A77 - Which target may be covered by this code?

[Grexx]

Dear all,
83 Sqn ORB gives an information about 11 Hampdens detailed on 16/17 August 1940 to bomb the target coded as A77. Unfortunately there`s no more information about the place that was bombed that day. My copy of 5 Group ORB has one page omitted (the one that covers operations between 14-18 August 1940).

So, could any of you give any clue that target may have been alocated to the A77 code?
Thanks in advance for any suggestions,

Regards,
Greg
