The funnel is black with a broad white band containing narrow red and blue bands separated by a wider white space. The flag is quartered blue and red with an overall white diamond. Its black ring encloses what appears to be a hammer and pickaxe crossed in saltire, surmounted by a small S with a lantern hanging from its tail. Brown 1958 omits the fine detail and renders the ring and emblem blue.
