The crown emblem apparently originated with Monarch Steam Fishing and survived to the end of the Grimsby company. The website assigns this funnel to fleet lists covering 1928–52.
ABC British Trawlers specifies a yellow-and-red crown.
The illustration follows the verbal description “yellow with red crown on a broad white band separating grey from black top”. Rosanoski says the livery apparently also served Rhondda Fishing and Wendover Fishing (Grimsby).
The website dates a change to March 1961 and describes blue with a white top separated by a white band, carrying the full-colour Monarch crown. Rosanoski notes that the website illustration differs from this wording. The site assigns C1170 to the “football fleet”, whose ships took team names from 1933.
Emil Hagerup and George Doughty, initially in coal, bought their first trawler in 1896. Their business expanded into shipbuilding in 1898 through Monarch Steam Fishing with James Schofield of Hull. John Marsden became involved during financial difficulties in 1901. The name became Consolidated Steam Fishing & Ice in April 1906 and Consolidated Fisheries in August 1927. Although shipbuilding ended in 1904, the fleet remained registered to Monarch until April 1906. The last trawlers were sold in 1978, some seiners in 1981; closure was announced on 26 November 1982 and sale of the last vessels on 30 December.
