There was/is no such thing as a 1940's vintage Winchester lever-action .410. Winchester did make a slide-action (pump) .410 shotgun called the Model 42 during the 1940s.
A PIG TAIL IS THE LEVER ON THE TOP OF THE GUN TO OPEN THE ACTION
The Winchester model 1901 shotgun was made between the years 1901-1920.
Winchester made a Model 1887 lever-action shotgun from 1887 - 1899. Norinco currently makes a reproduction of the Model 1887.
There were model 1887 lever action shotguns made by Winchester ( I have a 12 ga). These are worth in the range of $1200 to $5000 depending on condition. I am not aware of any Model 1886 Winchesters in a shotgun.
these 410 ga lever action shotguns were made from 2001-2006.
Less than 100 to multiple thousands depending on specifics.
The Winchester Model 1886 was primarily a lever-action rifle, not a shotgun. However, the Winchester Model 1887, introduced in 1887, was the first successful lever-action shotgun. Approximately 60,000 Model 1887 shotguns were produced during its production run, which lasted until 1898. If you're looking for specific production numbers for different models, please clarify!
You did not tell us what MAKE your shotgun is. The two 1895s that come to mind are a lever action Winchester RIFLE, and a Davenport shotgun, which had a prominent release lever right behind the hammer.
