coal scuttle helmet

British military slang from World War I referring to the steel helmet worn by soldiers — the Brodie helmet or 'tin hat.' 'Tin lid' follows the same logic as 'tin hat,' playing on the shape of the helmet as a lid placed on the head. The term captures the irreverent, dark humour soldiers used to cope with harsh conditions. Outside military history contexts it is rarely used today, though it appears in WWI memoirs, letters, and fiction.

WWI military slang for a tin helmet — the steel combat helmets issued to Allied soldiers that were far from stylish but very much life-saving. The 'derby' reference plays on the shape of the dome, reminiscent of a bowler hat (also called a derby). Soldiers' slang was full of this sardonic wit, finding absurd comparisons between brutal wartime kit and everyday civilian fashion. A small linguistic window into the dark humour of the trenches.

WWI British military slang for a tin hat, the steel helmet issued to soldiers. A straightforward descriptive nickname combining the material with the functional lid-like shape of the helmet. Now primarily of historical interest, appearing in accounts of WWI, military history, and period drama. Occasionally revived in British informal speech to refer to any hard hat or protective helmet. The term survives in historical memory largely because WWI looms large in Australian, British, and New Zealand national consciousness.

Trench derby was WWI British military slang for a steel helmet — specifically the iconic Brodie helmet introduced to British troops in 1915. The nickname stuck because the helmet's distinctive broad-brimmed, bowl-shaped profile vaguely resembled a derby (bowler) hat you might wear to the races, just beaten out of metal for surviving artillery barrages. It's a perfect example of how soldiers used dark humor and creative nicknames to humanize the brutal equipment of industrial warfare.

World War I British military slang for a tin hat — the steel helmet issued to soldiers as protection from shrapnel and debris. The term reflects the dark, inventive humor of WWI trench slang, which often reduced serious protective equipment to casual, almost dismissive nicknames. 'Tin dip' is less common than 'tin hat' or 'tin lid' but belongs to the same family of headgear slang that emerged during the war. Largely obsolete in modern usage.
