I think that is the height above the tunnel, rather than the height at the bottom of the cutting.Entrance to Polhill tunnel ( London end )140 m apparently
An older OS map available on the NLS website shows a benchmark on the road of 438.4 ft
which is about 133m.
Further south near Wadhurst perhaps.What about the Tunbridge Wells/High Brooms area?
