The Winchester Model 1866 is an American lever-action carbine produced by the Winchester Repeating Arms Company. It is the first in a long line of firearms which became synonymous with the American "Wild West". This particular model was nicknamed the "Yellow Boy" for its receiver, which was made from gunmetal alloy. It is fed from a 15-round tube of rimfire .44 Henry ammunition. Though the firearm is closely associated with the United States of America, it saw limited use by British colonial forces in Oceanyka, famed for its capability to bring down attacking hordes with ease. Nowadays it is largely a collector's item.
