Comment A staff photo (see link) shows uniformed staff wearing the standard 'BET' 'Magnet and Wheel' cap badge, which was presumably worn along with standard 'BET' buttons, though these are not visible on the photo.
Note that the Sheerness & District Tramway was the first electric tramway to close in Britain, it's premature demise brought on by a shortage of spares for it's German-manufactured overhead equipment during the First World War.
