There's a "Cluster of Nuts" which seems to be a farm between Altham and Clayton le Moors, near Gt. Harwood.
http://maps.nls.uk/view/102343952#zoom=5&lat=9567&lon=5607&layers=BTWhen viewing this map, Cluster of Nuts is situated to the left of the K which is part of the word Blackburn of which only the letters A C K and B are shown.
I'd hazard a guess that the road on the old map to the right of `C of N` is the A678, Burnley Road on a map of today.
