I have found an error but I guess I am too old to understand how to correct it.
If you go to "West Finchley" underground station, you will see a turning off Nether Street a few yards south of the station labelled Huntley Drive. It is an "L" shaped cul-de-sac (dead end).
Only the first part of the "L" shape is called Huntly Drive (note there is no "e" in Huntly so the "e" has to be removed.
The second leg of the street is not called Huntly Drive, it is called "Western Court". Western Court is not a block of flats but, irritatingly, is the name of an actual street.
I do apologise for not correcting it myself, I really have spent some time trying.
