The Colt 1877 Double Action (DA) Thunderer and Lightning revolvers, were the predecessors to the larger Colt Frontier and Army models that appeared the following year. The Thunderer - as per this record - was distinguished from the Lightning by being produced in the larger .41 calibre, rather than the Lightning's .38. The were the first of Colt's self-cocking, or double action revolvers, and both models were designed with the 'bird's head' style grips. The models were introduced in 1877 and production continued until c.1912. In style, the model shows obvious physical traits of the popular 1873 Single Action Army revolver, though in a smaller scale. Their models common terms of 'Thunderer' and 'Lightning' were infact not Colt designated names, but appear to have originated in 1878 with B. Kittredge & Co. of Cincinnati, Ohio - at the time, one of America's largest distributors of firearms.
