No disrespect, but I think your friend's having you on.
First, it's an Airborne wing, not a Commando wing. The emblems of
the Commando Battalion and SOF both have wings as well, but they
are different from the one on the pendant.
Second, Airborne's not really that hard. It's practically as easy
as falling out of an airplane. 
Third, any clerk or storeman working in the formation would know
Hendon Camp inside out - it doesn't mean much.
Fourth, what's anybody going to be able to show of the camp while
driving past? If he really is one of the guys, he'll have no
trouble bringing you in for an tour, escorted by one of the serving
personnel.
Fifth, you'll be surprised how many people out there pretend to be
from Force Line.
Last, if he's a Guardsman, he's a Guardsman. That job's tough
enough, and there really isn't any reason that he should pretend to
be anything else.
Nice to hear a commando giving the guards due respect. Good on
your Ged.
