Latest addition to the herd

[Eterry]

I picked what I thought to be 20 bore cap smoothbore last week. It has Birmingham proofs, I believe, 32' bbl, and measures 16 bore. I cleaned some grime from the stock; has plenty of figure and curl.
Covered in a good coat of rust and patina, the muzzle is thick and in good condition. Lock holds at half and full.
Fills a void: I have a 10, 12, 14, 20 and 26 (in parts) gun. The 16 will fit in nicely.

A very lively gun, I bet she don't weigh over 6lb.

Has what my mentor called a Hex Sign, a wedding band on 5 flats, and a patten breech. Is the bottom flat at the breech engraved like the others? I see lots of faint engraving on the barrel. Maybe I'm just tired. I hope @Feltwad , @TFoley, @Britsmoothy and others chime in. The crown jewels she isn't, but some info will help.
I'll work on removal century and half of grime.

Can't help sorry. Looks in good condition though. Especially the bore.
What letters on the lock plate do you see?

Gun is a typical Birmingham made gun of the late percussion period say 1845-1855 period The barrel is also standard with a baluster turn and 32 inch's in length I could not make out the name on the lock for which I may have given the approximately date also it could have been a traditional maker or even a ironmongers gun To clean the gun first relay the ramrod pipe and ramrod thimble {2number} clean of the barrel rust using a fine wet and try and polish bright for the bore this is best to remove the rust or pitting by lapping with this done next prepare the barrel for browning
I have found that the best load for this 16 bore gun considering its weight is 2.1/4drms of FFg to 1oz of shot

Looks like she should come around nicely.

"I have found that the best load for this 16 bore gun considering its weight is 2.1/4drms of FFg to 1oz of shot"
@Feltwad.

I recall the book I read regarding Double rifles and Game Guns. They had a bespoke cased single barrel rifle in 16 bore percussion made for a member of royalty.
The suggested load from, I believe, WR was 60grs powder for a round ball.

I thought 2 things; either the powder of the day was much more powerful or we load our guns much heavier than 200 years ago.
I'm a ways from shooting her, but that sounds like a good load for such a lively gun.
Thanks.

In the early 1970's , these shotguns were still to be found . I owned a nice 20 ga. just like it. Paid $100 for it , just to study it. Sold it at a m/l shoot for a little profit , but I got from it what I wanted.

I have a basket of LC Smith barrels I bought years ago. 16 and 28 bore, and 28" bbls. This one would serve well as a pattern for the wood. With a back action lock.

Nice find @Eterry I'd like to find similar in a small bore, like .410 or .45...
May we please see the inside of the lock amd details of the hooked breach?

Also, what do you look for as a "go or no go" indicator/s for whether or not one of these will be serviceable?
I might have looked at that breach/nipple area and passed on this, but I'm not experienced in this aspect.
