1)Above the A3123 find a band or group
2)The B3137 show it's for ladies only
3)Find a Liverpool BR station near Snigs End
4)Across the channel, is Queen Beatrix it's Queen?
The A3123 is only about 6 miles long and runs east/west just south of Ilfracombe.
Berrynarbor is a village 'above' the A3123 but I cannot work out whether/how that might fit the bill.
