With a serial number preceded with an "S" , I'm betting it was SKB of Japan
around 450.00
They were made in Japan by a firm called SKB.
You can find these numbers in the manual that come with your gun. They are also present on the handle of the gun.
Manuals for SKB shotguns are available online at the SKB site under Parts. See the related link below.
