That looks like a nice old gun to try and resurrect, as long as it is mechanically sound (wall thickness, tight, on face etc) or could be made so with minor effort; some of us have an appreciation for old guns which may yet continue to serve their masters with a little TLC and therapeutic (both for gun and master) tinkering. Good luck.
If it was all about perfect condition and efficiency, none of us would hunt with old guns. None of us would have any hobbies.
*Ignore* the nayayers who contribute little but their scorn.
