Winchester Model 1887 Shotgun
from Girls' Frontline
Origin
United States
The Model 1887 was the first truly successful repeating shotgun. 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 firearms 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.
