Voici ce que disait Gellermann à ce sujet:
"172 Fulton St., 7579 E. 13th St., New York, NY 18501855; Carhart, Needham & Co., 97101 E. 23rd St. 1861, 1865. See Needham Piano & Organ Co. Founded 1846 in Worcester, MA by Elias Parkman Needham and Jeremiah Carhart, moved to Stanton St., New York in 1848 and in 1850 moved to 13th St. between Third and Fourth Avenues, New York, occupying a part of John B. Dunham's piano factory. In 1855 Samuel C. Swartz was admitted as a partner and the company became Carhart, Needham & Co. In the same year the factory was moved to 143147 E. 23rd St. Swartz died in 1865 and the name reverted to Carhart & Needham until 1868 when Carhart died. The company was then renamed E.P. Needham & Son. In 1880 Needham sold his patents and "practically" retired. Serial numbers:
1846 - 642 1853 - 2090 1860 - 4386
1847 - 820 1854 - 2520 1862 - 4970
1848 - 940 1856 - 3000 1863 - 5200
1850 - 1400 1858 - 3300 "
S'il est nommé Needham seulement, c'est sans doute qu'il a été construit entre 1865 et 1880 comme indiqué ci-dessus.
