Jmb, I spent a lot of time in Campbeltown during the war, but I'm sorry to say I can't answer your questions. I didn't know where the village of Ugadale was, The only "Ugadale" of which I was aware was the Ugadale Arms Hotel, and come to think of it I'm just assuming I was aware of it during the war. Around Machrihanish during the war of course, was all Fleet Air Arm personnel and training flights.
I knew the "Old Quarry", too, of course, but not what the RN had to do with it. After the war the old lifeboat building there was used by the local RN Cadets.
