I have arrived here rather late so I hope tink.tech is still around. There is confusion about the location because it is near the junction of three parish boundaries. I think it was probably a small army camp, perhaps used by soldiers manning artillery defences etc. in an area which is a few miles east of the manufacturing district of Rotherham and Sheffield. At another camp further north-west in Rawmarsh, at the end of the war the camp was abandoned and homeless people just moved in. There, the urban district council ended up managing it as "council housing" until people could be re-housed, which took more than 10 years.
This site is shown on an OS map, a 6-inch provisional revision of 1948, which shows buildings added since 1928 as unshaded hollow blocks:
https://maps.nls.uk/view/100950197The camp is north of Todwick village, unlabelled. Look at the upper centre of the map, by a T junction on Common Road, there is a cluster of hollow buildings with a 325 ft contour running through them. (Grid ref 498861) This is in a late 18th cent. landscape of commons enclosures with straight roads which tend to turn through angles at parish boundaries. The Todwick boundary is just south of the camp. The camp is actually in a corner of the parish of North and South Anston, hence the electoral registers. A short distance to the NW, Common Road becomes Long Road across Brampton Common which leads to the village of Brampton en le Morthen. Nothing remains on the site now - an arable field.
