Follow up question:
The internet tells me G-AZSC is now based near my house and is dark blue marked ’43’ and ‘SC’.
Dark Blue Harvards seem to fly over my garden all the time. Rarely close enough to see numbers of get a photo, but this summer I got this shot:

72 on the tail.
Is ’72’ G-AZSC with a recent paint job? If not can anyone identify the aircraft?
TIA!
