Did you a mean Remington SPR220? Remington SPR220 is a side-by-side shotgun. You can get a schematic of this fine shotgun from down loading the owners manual from Remington. Kathleen
The barrel code stamp will tell you, see related links.
From the data code stamped on the barrel. Check the Remington Society of America web site manufactured date link.
Go to remington.com, then go to the "support" menu, choose parts. From there you can find the schematic for the 1100.
On the left side of the barrel you will find the date codes, which are a combination of letters. The serial number doesn't do a whole lot of good on Remington dates. Remington 1100 shotguns in 12ga will bring from $175-$350 depending on features and condition. sales@countrygunsmith.net
