Filbert - that is CRANFIELD - not Cranwell - the 'rmcs' bit at the start of the address is Royal Military College of Science - um, Shrivenham I think.
Therefore we don't want to be tarred with this rather new Walter. You can keep him. Which ever regiment he/she claims an affiliation with.
Are we sticking with Walter or could it be a Troll? Panic! Oh - sorry - not American, are we?
