Welcome Clint, and if you're the fella in Lee's Summit word is you do nice work!
You no doubt saw Brad's mismatched Nitro Special on p.1. At least both your barrels are
Chain, but the right is a mess. From Nov. 30, 1895

"The Gun Making Industry How Shot Guns Are Made and the Process Through Which They Pass Fully Explained"
The beginning of the manufacture of a gun is the barrels, and it is generally known that no barrels are made in this country except the rolled steel, which is used on the Winchester gun.
All gun barrels are now imported, although an attempt was made a few years ago to produce them in this country, but with only partial success. England, Germany and Belgium supply most of the barrels, the latter country doubtless producing the larger quantity. All gun barrels, whether imported direct from the makers in Belgium, or through an importer in this country to the gun manufacturer, are received in rough tubes, which very much resemble a couple of gas pipes, but being somewhat larger at one end than at the other. These barrels or "tubes" as they are called, are merely
tied together in pairs, with small wire and 40 to 50 pairs are packed in a box.
There are many kinds of barrels and each have several grades, the cheapest being the twist, of which there are a number of classes. Laminated steel is a better quality of barrel, while the Damascus barrel, which is the most popular, has the greatest number of grades of all. Many persons suppose that a barrel is a strong one if it is Damascus, when, in fact, a first-class twist barrel is superior in strength to many of the cheaper grades of Damascus.
When the tubes arrive from Belgium they
clearly show the figure of the twist or the peculiar curl of the Damascus and the different qualities can thus be distinguished from the construction of the material shown, even in their rough state. These tubes are paired, trued up or straightened out if crooked and soldered together: the lugs on the bottom/ and the extension on the top being brazed in, but the top rib and under rib are hard soldered. The barrels are then very rough and are placed on machines, which cut down the lugs to nearly the required shape and size.
Actually, until the tubes are finished and colored, it can be difficult to identify the pattern. SO, a pair of tubes were likely wired together in Belgium, shipped to Ithaca, then joined, fit, finished and colored before the mis-match was apparent.
I'm in awe of the barrels guys at Parker as to their ability to match the D4 and D6 'Turkish' barrels.
