A modern reproduction of the Winchester M1887 lever-action shotgun
Early attempts at repeating shotguns invariably centered around either bolt-or lever-action designs, drawing inspiration from contemporary repeating rifles, with the earliest successful repeating shotgun being the lever-action Winchester M1887, designed by John Browning at the behest of the Winchester Repeating Arms Company.
Lever shotguns, while less common, were popular in the late 1800s with the Winchester Model 1887 and Model 1901 being prime examples. Initially very popular, demand waned after the introduction of pump-action shotguns at the turn of the century, and production was eventually discontinued in 1920.
One major issue with lever-actions (and to a lesser extent pump-action) was that early shotgun shells were often made of paper or similar fragile materials (modern hulls are plastic or metal). As a result the loading of shells, or working of the action of the shotgun, could often result in cartridges getting crushed and becoming unusable or even damaging the gun.
Lever shotguns have seen a return to the gun market in recent years, however, with Winchester producing the Model 9410 (chambering the .410 gauge shotgun shell and using the action of the Winchester Model 94 series lever-action rifle, hence the name), and a handful of other firearm manufacturers (primarily Norinco of China and ADI Ltd. of Australia) producing versions of the Winchester Model 1887/1901 designed for modern 12-gauge smokeless shot shells with more durable plastic casings. There has been a notable uptick in lever-action shotgun sales in Australia since 1997, when pump-actions were effectively outlawed.
