From Through The Brazilian Wilderness written by Theodore Roosevelt in 1914 regarding the Roosevelt–Rondon Scientific Expedition down the Rio da Dúvida (later the Roosevelt River):
"For arms the naturalists took 16-bore shotguns, one of (George K.) Cherrie's having a rifle barrel underneath. The firearms for the rest of the party were supplied by Kermit and myself, including my Springfield rifle, Kermit's two Winchesters, a 405 and 30-40, the Fox 12-gauge shotgun, and another 16-gauge gun, and a couple of revolvers, a Colt and a Smith & Wesson."
