Climbin 21 ain’t cheap. Is that what the extra hole in the receiver by the hammer screw is for ? 
  

That hole by the hammer screw is for the saddle ring, the carbine isn't drilled for the Lyman 21, that would be just at the end of the rolestamp 
  

Thank you cj for that information.
Well now im really confused. Why would the rear sight be modified if not for use with a receiver sight?
If the hole is there for the saddle ring, would that mean this would have been a factory SRC? Or are all carbines drilled for the saddle ring?
  

Yes, it's a SRC, one of its owners removed it, maybe didn't like the clinging noise. You often see the 95 carbines with the handguards removed, the cutouts for guard clips are visible on sides of forearm, if no cutouts, then it was ordered without handguard

Ahhh, yes thanks of course. That carbine appears refinished?
  

Yes, both metal and wood, and missing the forearm cover

Steven and ccomo,  In the FWIW category, my 1895 musket in .30 Gov't of 06 has a similar modified rear barrel sight.  However it also has the model 21 type receiver sight.  Getting the ladder and replaced blade sight out of the way permits unrestricted views through the receiver sight.  I've always considered the rear barrel sight to have been a modified, regular carbine or musket sight.  Seeing the second version now makes me think it may have been some commonly held "good modification".   Tim.  
  

I'm inclined to agree that the rear sight was modified in order to make use of a No. 21 receiver sight. Thanks for that suggestion Tim. Whoever modified the sight thankfully didn't do a hack job. Now to decide if I'll look for a ladder and get the sight back to its original configuration, or track down a Lyman model No. 21 sight and keep the sight the way it is.

Need help identifying this rear sight. It looks like the base is similar to the 50-B but with a folding open style notched sight.

I have yet to receive the rifle, pictures are taken from the auction listing.

That Porter sight looks first rate. The Ross rifle was ahead of its time and quite popular in Canada, England and used in Africa.
The military version was used  selectively by some in WWI. Assembly and disassembly of the Ross rifle has to be done carefully; the design does not suffer fools gladly. Improperly assembled, a Ross rifle was indeed somewhat  hazardous to the user.
   

Sir Charles Ross and his rifle had similar personalities. Neither suffered fools gladly, as you say.

If you mis-assembled the bolt, you could fire the rifle with the bolt unlocked, scoring an "own goal" as the bolt came back through your head. 

The last words uttered by Sir Charles were to an attendant, immediately after which he rolled over in his bed and died:  "Get the hell out of here."

My kind of Scot.
