So Lewis, you have found me so to speak.
About time for your first clue.
I have a number of display board magnetics that I took from Phillip's board in his room.
You will find this at N51 45.259 W001 15.199 outside the house of one of the greatest Savilian Professors. Not quite, as that is No7 so try No8.
It has a number on it, lets call its value H.
