This gun was probably made c. 1880-1900, possibly as late as 1914.
Depending on condition, between $50-$150. W. Richards was a brand sold by Sears around 1900, and was playing on the name of an unrelated very high quality English gun, the Westley Richards (no relation) Laminated steel was the term used for a form of twist steel barrel. These should NOT be fired with any modern smokeless ammo- and should be inspected by a gunsmith before shooting anything. But it would look great over the fireplace.

Please list all the markings on the shotgun. Harrington & Richardson were producing hammerLESS double shotguns as far back as 1882. sales@countrygunsmith.net

Possibly a BAYER 12 Gauge side by side ? Mine has two hammers and triggers. The trademark of a knight on horseback is inscribed on both barrels, and also 'Anc.Etabl.Pieper Herstal Belgium' inscribed on the barrel rail. Have any older shotgun checked by a gunsmith before using, it may not be up to modern loads. I cant find any other markings except for Occidential stamped on the side and it has a police shield on the but of the handle
It may have laminated barrels or short chambers which would not be safe with any but the lightest loads equivalent to shells that were available 75-100 years ago. Have it examined by an experienced gunsmith and follow his advice.
