Found at an estate sale, don't have a clue what it is or its value, "Sylvester Steel Lock"? ...
remove the barrel and look under it for stamping of either english or belgium proofing marks.
.
The proof marks appear to indicate a Birmingham (England/Britain) Proof House definitive black powder proof for shotguns.
"CB" may be a maker's mark, but IDK who.

Now I lay me down to sleep
A gun beside me is what I keep
If I awake, and you're inside
The coroner's van is your next ride
Nice old "piece", that if from Birmingham would place it somewhere around the 1850's. I have a "Cape" gun that is 12x.45 cal (BP) with similar markings. Do you intend on firing it? If you do, I would recommend FFg (only) black powder with a starting load around 50gr with a 1 oz or less of shot for "starters". Look up Birmingham firearms; it tells of a pretty interest history of the company. Congrats on your find.
