Moses Slater (1826-1899) was in partnership with Godfrey Robert Martin (ca. 1835-ca. 1900), under the trade name of Slater & Martin, from 1871 to 1874. Subsequently, Slater continued to run the business, located on Courtlandt Street in New York City, under his own name, until 1888.
The tube arrangement of this cornet is identical to the four-valve instruments by Isaac Fiske (NMM 6884) and by E. G. Wright (NMM 7073). However, the pitch-change from B-flat to A, which is accomplished by activating the fourth valve on Fiske's and Wright's cornets, requires a change of the main tuning slide on Slater & Martin's instrument.
