I have identified it on the OS Landranger map. Pity my poor health prevents me from scaling those close-packed contours!
Do your records show anything on Hudson AM791 and Hampden P1174, I wonder?
I’ve often wondered what movements there might have been at the airstrip at Glen Brittle. It had scheduled tourist flights from Renrew (DH Rapide) prewar, but as Glen Brittle House was a commando training centre (I believe) I wonder if there were any army communications flights.
