What Tmitch said. Ive D&T’ed one original. But it was not really in collectors condition. It was a real hunter’s grade rifle.
I will go on to mention that Redfield made a Lyman look alke sight. I do not know if they have the same hole spacing or not. I do not believe it was all that popular a sight as the Lyman. So chances are if your 95 receiver has the extra hole, it’s probably for the Lyman.
Lyman actually made two sights like the #21. The other was the #38 (I believe thats the right number). But the hole spacings were both the same. The latter sight was an improved version with a adjustable windage knob.
If you are REALLY interested in 1895’s I suggest this new book!!!
