I hope you get her back mate, she is a beauty...
I have just moved right out into the countryside, as in just this house alone no neighbours and I am so worried my 90 will be taken.... so I have bought a chain thats attached to the house / axle, two trackers and a dummy tracker box with LED light, steering lock, clutch claw and an immobiliser to boot... takes me ages to get going in the morning but its worth it i think.
I love the look of your landy and I truly hope you get her back, I will keep my eyes open incase it travels through Oxfordshire.
