What is the age and value of a 12 gauge with markings for Whippet Model C HSB and Co from J Stevens Arms Company?

Answer 1

If it is a 12 ga side by with a logo of a dog leaping through a circle and "WHIPPET" along with "H.S.B. & CO." it's a J. Stevens made for Hibbard, Spencer, Bartlett & Company of Chicago, Illinois. Likely comps to STEVENS 311, if it has no serial number it is pre 1968. It's a shooter with no collector value appx $150-$250 depending on condition, slightly less than the Stevens due to off brand production. I have the same gun in 30" 2 bead, full/mod and use it as a "Buddy" gun for trap range.
