Gunsmithing knowledge?
 

Appologies for a very brief introduction. I was an interested and somewhat active forum user about 10 yrs ago when I was hunting with a 10 ga hammer gun. 1884- l grade, perhaps I sold it to one of you.
I recently got the bug again and have landed a 16 intended for the Maine woods. I was casting about for a gunsmith in Maine who might advise me during the minimal 3 day inspection but didnt have much success. I did speak with Steve Dalzell who was willing to assist but is on the other end of the state, so I am presently weighing things on my own. I wouldnt shoot this without more info, but as the time is ticking... rst loads if it comes to that of course.

I will attempt to post some photos, but generally the thing ive noticed which is most alarming is at the breech face of the barrels. It appears to be a slightly upset ring of metal where the rim of the shell rattles around on firing. There is also evidence of an outer ring near the barrel od.
The chambers measure .745" and so are somewhat oversized. A regular rst shell does have free play in the chamber.
Im not sure how well the photo evidence will transfer but please have a look and let me know if this is a major red flag. The gun also exhibits some fracturing in the wrist which was known when I bought it but could also speak to heavy use.
Additional photo of green leaching from solder on barrel flats, barrels ring ok.
Thanks in advance

I see nothing unusual in your photos. Lets wait an see if others see anything of concern.

The barrels look like they8been sleeved.

A little more info would be helpful, SN it can be checked against the book, grade of gun, picture of barrel flats. Is it tight on face?
Possible sleeved, but ???? The dogs head seems rather pitted, so maybe the chambers were too, and honed?
The verdigris on the bottom of the barrel is from the brazing corroding, not unusual.
A definite case for inspection by a qualified smith.

The barrels are NOT sleeved. It just looks like they have been overly cleaned up. and the hard edges on the chamber/rim have been lost.

If you don't like the look of it, then return it. There are plenty of other fish in the sea.

Were the bores or chambers typically case hardened? I think your opinion is correct, what looks like a sleeve is actually a micro burr, or peening if you will. Assuming that type of thing wouldnt in itself prohibit shooting I would probably keep it, given all the other variables.

no - and the barrels were blued on the outside only

The .745 is correct for a Parker 16 ga. The ring you talk about appearing on the rim also appears on the extractor so I very much doubt it is sleeved. The green you talk about is caused by moisture in contact with the silver soldier joint at the breech and is not uncommon.

If you zoom in on the pictures of the end of barrels you can see another circumferential line near the od. Any thoughts on what to make of that?

Nope!
