One alteration that won't detract from the gun would be to replace the striker with one that has an aperture sight fitted to it, and keep the original striker for posterity if complete originality is ever called for. Those sights are old technology and no longer made (except for a guy somewhere who's name and location eludes me) , and are a little spendy but certainly no worse than a quality scope and mounts would be. Lyman made a dandy, as did Rigby in the UK (which sight is reproduced by the guy who's name I can't remember). They work, I've used a couple over the years. The aperture focuses light into the eye allowing better front sight and target definition. If it's too dark to use such a sight, it's probably too dark to be in the woods trying to shoot a deer anyway- better to have a second cup of coffee instead.
Sometimes you gotta wonder how the ancients ever managed to kill deer without the aid of space age optics.
