Mr. Petrov:
Thanks very much for the sight photos. It's an unusual tang sight. Do you think Mr. Schaefer built it from scratch, or is there another maker's mark or name on it?
There are no marks on anything on the rifle save Schaefer's and the Owner's name on the barrel. I have no reason to think anyone but Schaefer built the sight. It's not like there are a lot of them to compare to, the only other one I have a picture of has a fold down "lollipop" one. I've got the word out looking for more before I build a rear barrel sight.
