The Winchester Model 1887 (Dellosso Shotgun) and Winchester Model 1901 are lever-action shotguns originally designed by famed American gun designer John Browning and produced by the Winchester Repeating Arms Company during the late 19th and early 20th centuries. The shotgun has become iconic for its use in the 1991 film Terminator 2: Judgment Day. Overview The Model 1887 was one of the first successful repeating shotguns. Its lever-action design was chosen at the behest of the Winchester Repeating Arms Company, best known at the time as manufacturers of lever-action rifles such as the Winchester Model 1873. Designer John Browning suggested that a pump-action would be much more appropriate for a repeating shotgun, but Winchester management's position was that, at the time, the company was known as a "lever-action firearm company", and felt that their new shotgun must also be a lever-action for reasons of brand recognition. Browning responded by designing a breech-loading, rolling block lever-action. To Winchester's credit, however, they later introduced a Browning designed pump-action shotgun known as the Model 1893 (an early production version of the model 1897), after the introduction of smokeless powder. Shotgun shells at the time used black powder as a propellant, and so the Model 1887 shotgun was designed and chambered for less powerful black powder shotshells. Both 10 and 12-gauge models were offered in the Model 1887; 12-gauge variants used a 2 5/8" shell, 10-gauge variants fired a 2 7/8" shell. The standard barrel length was 30" with 32" available as a special order. In 1888 a 20" barrelled version could be ordered and Winchester offered the shotguns with Damascus barrels. Model 1901 By 1900 it was soon realized that the action on the M1887 was not strong enough to handle early smokeless powder shotshells, and so a redesign resulted in the stronger Winchester Model 1901, 10-gauge only, to handle the advent of the more powerful smokeless powder. A 12-gauge chambering was not offered, as Winchester did not want the Model 1901 to compete with their successful 12-gauge Model 1897 pump-action shotgun. Other distinguishing characteristics of the Model 1901 are: The shotgun was offered with only a 32" barrel. A two piece finger lever with a trigger block to prevent accidental discharge. The Winchester trademark stamp was moved to the upper tang, behind the hammer. The choke type was stamped on the left side of the barrel near the receiver. Although a technically
