The Remington Model 17 (and their similar Model 31) were some of the finest pump-action shotguns ever made in terms of function, material, finish and workmanship. As Crawdad1 and entropy noted, these Remington shotguns, along with relatively affordable but finely made pumps like the Ithaca Model 37 and Winchester Models 97 and 12, were made in an era the likes of which, sadly, will never be seen again.
Very nice find, bushmaster1313, and at a great price, given the relative scarcity and fine condition of your Model 17.
