We're talking different languages.
My coordinates from the AIP are degrees and minutes, yours are degrees and decimal degrees. So
N 51° 21' would equate to 51.35 degrees, for example.
As it happens, I've just been playing around with a conversion from OSGB lat/lon to OS Grid, and produced this bounding box based on the AIP coordinates:
Height and width are 1 minute of latitude and longitude, respectively, centre of the box is the above-quoted coordinates.
As for whether there is any discernable sign of the radio range remaining today, we would be looking for 4 points spaced more-or-less equidistantly around a 600 foot diameter circle.
Here's an example of one in the USA from GE - it looks like somebody has helpfully planted trees in the holes vacated by the antennae.
The Epsom one may well be under housing, or the golf course.
