You've got a point there.

I've read this over and over and it's not making sense to me.

What kind of instrument was the 'smith' using that can measure, and differentiate in ten thousands of an inch. Why is the Right barrel, one tenth tighter (.0001") than the left, called Modified, when the Left barrel (I agree that .026" is full), one ten thousands more open is called Full.
I agree that a conventional micrometer can measure in tenths (.0001") but I am not aware of gunsmiths, or anyone outside of laboratory conditions, measuring bores down to a tenth.

I'm guessing those measurements are MBWT...

You knew that before you started this thread.

Just a hunch but I think Mark reported that the barrel thickness for both is about .026 for both barrels. Then quickly indicated that barrels were modified and full without giving the constrictions. If both barrels were .0266 and .0265, I'd say both were full and full. I have not had my barrels measured and have never seen this piece in person but did see old Larry measuring a barrel thickness. His was an analog gauge but not certain why it can't be digital.

Btw digital weight scales are an inferior technology. I had one that was constantly wrong. Have an old analog bathroom scale that I use that gives me a number I much prefer.

I think "Old Larry" oversimplifies what he's trying to demonstrate by leaving out several very critical steps.

Most likely true, Dean. Still, what instrument, (in a gunsmith's tool kit) measuring either bore diameter, or wall thickness, gives a one tenth resolution?

Hosford gauge

I have a 16ga DHE, with sling swivels, and I have seen several other Parkers with them. A fellow I consider fairly knowledgeable in the oddities of Parkers, who also happens to be a former President of the PGCA, indicated to me that he felt they were original, Meriden, installed swivels. That said, I have yet to see a research letter where either the order book, or stock book has noted that swivels were installed on the gun for which the letter was written. I'm sure there are such entries, just that I've yet to see one.

I think Rich Anderson has a gun that letters for sling swivels
