A rocking melodeon, also known as a lap organ and an elbow organ, stamped on nickel plate near swell lever: "D. BARTLETT / MANUFACTURER / CONCORD N.H." Mahogany with flamed maple plates, eight horn-rimmed soundholes (three rims missing), 4-octave chromatic range with large ivory buttons and wood plate indicating the notes. The lid of the outer box is lined with an advertisement which is a pretty amazing document relating to the formation of the new company, seeking investors, mentioning winning several medals for their instruments, etc. and which wonderfully includes a handwritten note in pencil saying that the instrument was bought in 1844 by J. L. Thomas in New Bedford (repeated boldly on side of lid).
