RCS, Thanks for posting those photo's. That's a very impressive collection you have at your fingertips. Makes a great reference! By comparison, I only have one other 1903. It's another RIA made just after the heat treatment changes. (I did own a sporter when I was in high school that's long gone - remember the days when a high school kid could buy a rifle?). Anyway, I did pull my later 03 out to do those comparisons, but having the uninstalled parts to look at is even better.

The photo's I shared of the front and rear sights (& bases) were intentionally taken to show the specifics that were unique to the ramrod bayonet barrels that were shortened for the 30-06 cartridge. As you know, those things (that I am aware of) are the front sight base pin location, the exposed slot/keyway at the rear of the front sight base, and the no longer used transverse groove visible through bottom of the rear sight base. Since those differences are expected, I figure there must be something else visible in the photo's to have a determination made they were installed by a non-professional. Since I posted this thread so I could learn things, I'd like to know what those things are. Thus my earlier question for elaboration. When you're looking at these photos, do you see anything that raises a flag?

Unless I am seeing things, the transverse pins for the rear sight fixed base and the front sight base are visible. They would not have left the arsenal that way. Also, I am wondering if the spline on the barrel for the front sight base is present.

Thanks for clearing that up for me. You're eyes aren't deceiving you, the pins are visible. The spline does seem to be present. I won't be taking the sight off to verify, but there is something solid filling the slot about the expected depth of .2" in.
