DescriptionAn anti-tank pimple and one anti-tank cylinder first recorded by volunteers undertaking the Defence of Britain project (the anti-tank cylinder has since been removed and only the anti-tank pimple remains). The anti-tank pimple is a freestanding concrete block with a protruding steel bolt in the top surface . This pimple would have been linked to at least one other with a length of chain to serve as an improvised road block.
