This is quite likely a one-of-a-kind drum. Produced by the C.G. Conn Company as a special order/special occasion drum and/or a presentation drum purchased by, given to, or presented to H.M. Loomis at the time of the World’s Fair in 1893.  How this drum was acquired by H. M. Loomis is unknown but the rest of the provenance is engraved on the shell of the drum: “H.M. LOOMIS WORLDS FAIR 1893.”
