you also have the 1901 rear sight on your rifle, while this may have been added during a repair/upgrade of the rifle, and can be left on the rifle, it is not the one for that rifle. This may also replacement of the handguard for the correct site, but that would be your call in the long run. you have a very nice rifle over all and i would leave it as is, and it looks like it may have been reblued at some point.
