As I posted on the other site when I directed you here --
128056 is a Quality 2 (the 2 above the serial number on the watertable) hammerless or GH-Grade (the G below the serial number on the watertable) which is a 1904 vintage gun according to the serial number chronology in the book The Parker Story. The GH-Grade of that era came with Damascus barrels. The gun is a 2-frame gun, the 2 on the bottom of the barrel lug. From the picture of the barrel lug we can see the gun has been fitted with the post-1910 bolt and replaceable bolt-plate on the lug, so it was back to Meriden sometime after 1910.
146931 is a Quality 3 hammerless or DH-Grade of 1908 vintage. The DH-Grade guns of that era normally came with either Damascus barrels or Titanic Steel barrels. From the picture of the barrel lugs we can see this gun has also been fitted with the post-1910 bolt and replaceable bolt-plates on the lugs, probably when it was back to Meriden to fit the extra set of Twist barrels. The 3 on the bottoms of the barrel lugs indicate it is a 3-frame gun which were most often 10-gauge, but it appears that the set of Twist may be smaller like a 12-gauge. Often when a customer sent a gun back for an extra set of barrels he opted for a lower price set like these Twist barrels which are standard for the Quality 1 or PH-Grade gun. That extra screw through the trigger guard on 146931 is not a good thing.
We need a dozen or so more pictures showing the stock and forearms and we need to see the muzzle end of the ribs on the barrels to tell if any have been cut which would greatly effect market value.
It appears that 146931 got a PH- or VH-grade stock at some point in its life, and of course that Remington butt plate with the Phillips screws is non-original.
Good job on the additional photos. However, one thing I was looking for were pictures of the top rib at the muzzle to see if this little unmated band is present, indicating the barrels haven't been cut --
