The alignment of the number stamps looks like it was done by machine, but it wasn't.
If you could post a few photos of the muzzle area and other side of the rifle and receiver, we might be able to tell you a bit more.
It would probably have had the two position peep sight (300/600) as production of the MkI backsight fell behind production of rifles fairly early on.
Looks from this distance like it was probably restocked in UK service, and painted, so your call whether to leave it "as found" or "restore".
Two groove barrel of five groove?
