  Zoom in to OS 1:50,000  and  1:10,000 OS Street View  
  Note the co-ordinates in the top right corner are 6 figure National Grid co-ordinates.
To convert them to 5 figure co-ordinates take the first EAST: digit and the first NORTH: digit.
In the Swaledale area they will be one of four combinations:  35 = NY      45=NZ       34 = SD      44 = SE
These four 100km squares meet 1km east of Surrender Bridge.

Example Reeth:  EAST: 403853   NORTH: 499279    = SE 03853 99279
Example Langthwaite Bridge:  EAST: 400533   NORTH: 502453    = NZ 00533 02453
