The receiver is the largest metal piece of the shotgun, in other words, the frame of the shotgun. All the other parts, such as barrel, stock, bolt, etc- attach to the receiver. With modern firearms, the receiver will be marked with the serial number. Legally, the receiver IS the firearm- all other parts are simply parts.
The shotgun you own is a Savage/Stevens 520 shotgun. It was sold by Sears under a Browning patent. They first started making these shotguns in the 1920s. You can probably find more info by looking into the maker. To find parts, try Numbrich. Their Web site is www.e-GunParts.com. They have diagrams of the parts and you can find most parts you need there.AnswerThe shotgun is at least 75 years old, because the last year it was made was in 1930. 1915 to 1930. Then came the 620 and 621.
