Guns bored after market show a decided taper or "dip" to the parallel line from breech to muzzle. And as the case with Fox HE grade guns, most were marked "3 " but not all of them.

I've recently become interested in these late Parker 1-1/2 frame/3-inch Long Range guns. I highlighted part of Kevin's post and question whether they really were straight along the full length of the barrel from
breech to muzzle? The width across the 1-1/2 frame barrel breech is about 2.290" and width across the muzzles (32” barrel) is about 1.610". And if perfectly straight and without a transition “swamp” for at least a few inches forward of the breeches that might make for a decided heft and odd look to the back end of the barrels.
Or is it, that the barrels are straight tapered without a swamp from a point beginning some inches (10-12?) ahead of the breech and out to the muzzle?
Can someone with an original late 12 ga/3-inch gun on a 1-1/2 frame please check this for us?
