I visited what remains of a Battery Gunnery Range at Islandmagee in County Antrim yesterday and was very pleased with what I found. As well as the usual pieces of concrete there are 4 metal bases/mountings for the large guns. I suspect they would have fired at targets towed by aircraft over the sea. I have been unable to download the pictures onto this site and would appeal to all you knowledgeable folks to go to Home - Second World War in Northern Ireland and click on County Antrim Park 2. Scroll down till you find them. Its quite an impressive setup and I am interested to know what types of guns would have been used? Do the 2 types of mounting relate to 2 types of guns? Would the targets be air-tow or in the sea? Thanks.
