Context paragraphs:
Victory Park Historic District: The Victory Park Historic District of Manchester, New Hampshire, encompasses Victory Park, a city park laid out in 1838, and four buildings that face it across adjacent streets.  Originally called Concord Square, Victory Park was laid out by the proprietors of the Amoskeag Manufacturing Company who founded Manchester, and was first used as a common area, used by abutters for gardening and grazing.  The park was sold by the proprietors to the city for $1 in 1848, conditioned on making alterations that would transform it into a park.  The city did not immediately act on the required conditions, but it had by the 1870s become more parklike, with a fountain and thickly-planted trees.  The park was renamed after the First World War; its most prominent feature is the Winged Victory Monument to the city's soldiers in that war, designed by Lucien Gosselin and erected in 1929.  The park underwent a major rehabilitation in 1988.

Delco Electronics: Delco Electronics Corporation was the automotive electronics design and manufacturing subsidiary of General Motors based in Kokomo, Indiana.  The name Delco came from the Dayton Engineering Laboratories Co., founded in Dayton, Ohio, by Charles Kettering and Edward A. Deeds in 1909.

Evans Manufacturing Company Building: The Evans Manufacturing Company Building, also known as Metropolitan Supply Company Building, is a historic building located in Cedar Rapids, Iowa, United States.  The Brown-Evans Manufacturing Company, which made men's work clothing, was relocated from Sedalia, Missouri to Cedar Rapids when this building was completed in 1919.  It was built in the 4th Street Railroad Corridor, which had attracted various industrial enterprises in the years before and after World War I.  The Modern Movement building was designed according to the principles of industrial design of the time in light of the Triangle Shirtwaist Factory fire in 1911.  Its fireproof masonry construction was intended to lessen the risk of fires.  Storage of raw stock was located in the basement, cutting and storage of finished stock was located on the first floor, and sewing was done on the second floor and balcony.  Its open floor plan allowed for assembly line production.

Airco: The Aircraft Manufacturing Company Limited (Airco) was a British aircraft manufacturer operating from 1912 to 1920.  Airco produced thousands of aircraft for the British military during the First World War, most of which were designed by their chief designer, Geoffrey de Havilland.  Advertised in 1918 as the largest aircraft company in the world, Airco established the first airline in the United Kingdom, Aircraft Transport and Travel Limited, as a subsidiary.  A glut of war surplus aircraft and a lack of government interest in aviation caused the company to become unprofitable, and in 1920 it was sold to Birmingham Small Arms Company, who had its operations liquidated later that year.

A second-cousin took over the company when the founder died in 1900 and began making powered-cycles also under the Aeolus brand.  Production was interrupted by the First World War, after which motorcycles were marketed under the Bown brand until 1924.  The company was subsequently acquired by the Aberdale Cycle Company in the 1930s.

Colt's Manufacturing Company: Colt's Manufacturing Company (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt.  It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836.  Colt is known for the engineering, production, and marketing of firearms, most especially between the 1850s and World War I, when it was a dominating force in its industry and a seminal influence on manufacturing technology.  Colt's earliest designs played a major role in the popularization of the revolver and the shift away from earlier single-shot pistols.  Although Samuel Colt did not invent the revolver concept, his designs resulted in the first very successful ones.

Harold John Pye: Harold John Pye (27 November 1901 - 20 January 1986) was the son of William George Pye who, in 1896, started a company called W G Pye which manufactured scientific and optical equipment.  The firm prospered during the Second World War by manufacturing specialist equipment such as gun sights.

Harold joined the firm and helped to develop a new radio which proved so successful that the radio manufacturing side of W G Pye and the rights to the name Pye Radio were bought.

Pierce Schenck: Pierce Davies Schenck (d. 15 October 1930, Dayton, Ohio) was an entrepreneur in the metalworking business in Dayton, Ohio.  He used the garage behind his house on South Brown Street to work on automobiles and in April 1907 incorporated the Speedwell Motor Car Company.  Speedwell purchased and occupied a former Dayton Machine Tool Company factory on Essex Avenue in Dayton's Edgemont neighborhood, a site that later hosted a Delco factory.  The factory provided temporary space to the Wright Company in 1910 before the completion of its new airplane factory in west Dayton.  The Great Dayton Flood of 1913 inundated the Speedwell factory, destroying machinery and automobiles, and the company proved unable to recover and entered receivership in 1915.  Schenck later became president of the Dayton Malleable Iron Company and turned his focus to adapting high silicon iron alloys to practical uses.  This led to his establishing the Duriron Company, a name which he coined, in 1917.  It prospered through high demand for its products generated by the First World War and employed 1,500 people, becoming one of Dayton's leading industries.  His home at 414 Oakwood Avenue in Oakwood was designed by Dayton architect Albert Pretzinger in 1927.

New England Small Arms: New England Small Arms Corporation was a consortium of small manufacturers who coordinated their facilities for production of M1918 Browning Automatic Rifles during World War II.  The company was an unusual variation of United States conversion of small manufacturing plants from civilian goods to military armaments production.  Other manufacturers of this size typically produced firearm components on a subcontract basis for larger prime contractors responsible for assembly and delivery.  Boston Wire Stitcher Company of East Greenwich, Rhode Island, A.G.Spalding & Brothers of Chicopee, Massachusetts, Blake Manufacturing Company of Clinton, Massachusetts, International Silver Company of Meriden, Connecticut, National Blank Book Company of Holyoke, Massachusetts, and Elliot Addressing Machine Company of Cambridge, Massachusetts distributed tooling used for M1918 rifle production during World War I by Winchester Repeating Arms and Marlin-Rockwell.  Each company manufactured different rifle components and forwarded them for final assembly to a jointly operated facility converted to wartime arms production in Crompton, Rhode Island.  The corporation was created for M1918 rifle production and dissolved as members of the consortium returned to pre-war production when wartime procurement contracts were canceled.  The firm produced 188,380 M1918 rifles, or 90% of the total wartime production of 208,380.
