In the world of so many other things and Winchesters you get what you pay for...

The gun looks worn down and more or less a smoothbore(13mm shotgun)also..

A Turnbull restauration + a new barrel might do a little.

However for the low budget collector the gun might be a cheap intrance to a .50ex 1886 which in better conditions commands more.
