During World War II, 150 bunk beds were installed in the corridors and galleries of Battery Townsley. These were designated "Prison type" bunks because they were suspended from chains attached to steel brackets on the battery walls. The men who slept in them (or attempted to) would have heartily agreed with this description. None of the bunks remain inside Battery Townsley itself, where only the imprints of the mounting brackets remain, but there are still examples of these chain-supported bunks inside the PSR Room located down the hill from the battery. The attached photos show these bunks and examples of "standard" World War II folding-end Army bunks from which they were apparently adapted.
