Older SxS shotgun

[crabcreekhunter]

I inherited an older SxS shotgun and had been sitting in the safe for 10 years without much thought.  Any info on Joseph Butler from Chicago and SxS shotguns.  Older shotguns are not my thing so just looking for info.  Mechanically seems functional and all there, appears as a 12 gauge but not sure on chamber length etc.  any info is appreciated!
