'butlersrangers' - Thanks for all the outstanding help. I really appreciate it.

I will probably do much of what you are suggesting. To get the action "parts whole" I will purchase a 1896 or 1898 safety that simply pushes into place. I will purchase an 1896 cutoff assembly. (Yes there is a short pin pushed into the hole)

For the front sight I will likely purchase another 1903 Springfield banded front sight. I hate to remachine the barrel, but don't see another choice.

For the rear sight, I will clean out the front hole, reposition the 1902 sight, and fill the machined third hole. The diameter of the rear sight fits exactly on the barrel when it is pushed forward into it's proper position, suggesting that it was indeed a rifle barrel.

Any good ideas on where to get these parts?

Again, thanks for all the help.
