Let me say that is one fantastic looking rifle. It’s in the style of the old great rifles built by the British at the beginning of the 20th century, during the age of the great empires.
The rifle deserves to be rust blued. Also the holes drilled for the scope, just fill them with some nice screws to leave the option for a scope. A scope I consider perfect for the rifle and its classic lines is the Leupold 3x scope, see links below as and illustration (I have nothing to do with swfa):

Put back the original safety, if you are going to use it with iron sights. Another possibility is the use of a peep sight, which you can put on the holes you have drilled and it helps on accurate shooting.

You have done wonderful work I am very jealous.
