I dont recall there being windows in it. We used to use the area as a short cut between deneside and dalton le dale on our 'expeditions' Both the bunker and the sound mirror were bulldozed when the bypass was built in the mid 80's I lived in westlea during the 70’s and 80’s and often played in the area of the photograph. the sound mirror was there and there was also a concrete bunker burried into the hillside about 35-40 yards away on the downhill side. the bunker was about 8feet square and 6 foot tall.
