I have just come across these original photo's of Oxford: ROC HQ No. 3 Group. They were taken just after the closure of the the HQ back in 1992.

The building was partially demolished just after these photos were taken and much of the interior was regretfully thrown into skips. See SB's report here: http://www.subbrit.org.uk/rsg/sites/o/oxford/

Main entrance. Compare this photo with SB's photo of the demolition.

Operational well.

ROC Cluster map on the right with a UK/European Fallout chart on the left. I have copies of these!

The only things that apparently remain are the glass tote boards. I last heard they were propped up against a wall!

Certainly some rare photos of the exterior and interior.
Thanks for looking
