ORB for 21 HGCU Brize Norton.

Long shot but here goes.

I know a few people here go to Kew often and have photographed copied ORBs before. Does anyone by chance have a copy of 21 HGCU based at Brize Norton (one of many places). It’s AIR 29/526 in the PRO catalogue.

I’ve recently discovered a picture of a friends father (glider pilot) in a group shot taken there and I know he attended two courses. One I only have the course number, the other I have the date.

I wanted to try and match them up and see if I can help with with any course details to try and complete his fathers service history.
