Comment (by ChristopherSchmidt):

 London for a long time used a manual converter from OS X/Y coords to GpS
 Lat/Lon. This converter used Airy projection. Google Maps uses WGS-84
 projection. Although one may be more accurate on the actual planet or
 somethign (I don't know) many of London's points will not map properly
 onto Google Maps because of this.
