This has been a very good thread and I have been following it with great interest as I am getting ready to scope a 1903 I have (I was toying with another thread but thought there is lots of good info in this one):

Here are the pictures of the mount for it,not orginal to the gun but it will work( it says "-63B" on the rail.

What kind/brand scope and rings would you suggest I looks for?
Happy to provide better pictures and info of course.
Mnay thanks
