the lyman peep sight will be of low priority because they dont grow on tree's anymore. I understand that there will be some luck to find one. will look with one eye for an old rear sight with folding leaf's also.
period scope and new scope mount is easy to get compare with this.

the rifle's surface looks terrible, someone put cold blueing on it after rough it with sandpaper. remove this cold blueing gives terrible black dirt. I have to be very careful for not destroying the barrel inscrition .
