I am afraid I lied -
I said there another "project", and there is almost nothing to do to this one. I was told all sorts of issues.
I was planning to take the 10 bore Clabrough out to defend a friend's hunting property against an onslaught of geese, If I have the time this weekend to fix the one actual problem, this may go along. - The right lock needs a little jiggle to cock, I have seen this before on flintlocks, dirt or a burr in the notch may be all it is. On the Clabrough, it was simply a slight bend in the trigger tab where it met the sear arm.
This piece matches the letter perfectly - 9lbs on the nose - 32" barrels on a #2 frame, not that much drop, I put one of those thin neoprene velco pads on it and it fits fine.
I don't have a 10 ga bore gauge - but when I stick the 12 one down the tubes, it goes to its max reading. From there, I find the right barrel only compresses it a few thous, but the left presses in quite a bit. the letter shows a much lighter shot concentration in the right Vs the left tube. I have not found anything on Mr Armstrong yet, but I just started, I am guessing he saw a marsh or two over this rib.
The bores have modest coverage of light pitting and good thick walls if I decide to polish them at all. The outside has no rust, and I can see some nice figure in the twist under the patina. And they ring like the proverbial church bells.
Someone had rapped the left lock plate a few times with something hard, maybe to seat it, and left some tiny dents. From the original pictures, I had planned to have the filled by TIG welding and the plate redressed, but in person, they aren't that bad. So I may wait to see how much they bother me.

And the repro buttplate is too small - I'll get some careful measurements and order a better fit. The hammer screws are new.
so here it is -
never had a fishtail - that was a selling point
decent wood that needs a refinish, a very minor chip in the toe
the undersized buttplate
the dents
