On the subject of bayonets and blued blades:  I have a couple of 1894 dated bayonets with at least some amount of blue still showing.  The 1895 dated blades are, I think, harder to find than the 1894.  The report on blued blades is from April, 1895, but did they date bayonets with calendar or fiscal production dates?

On shooting this rifle, I would strongly resist the temptation till the stock is repaired - again.  In the meantime, I would look for help in finding a serviceable stock without a repair.  The repair you have is probably "of the period" and may even be the reason this rifle survived with only the change of the rear sight.  I have an identical repair on an L C Smith that belonged to my wife's grandfather.  He broke the stock in two sometime around 1900 and did shoot it successfully a couple of times, but in the 55 years  we've had the piece, the repair has loosened and I think shooting yours would have similar results.  I've been told that there are modern methods that may save our shotgun, but to break it again by shooting, may make a another fix impossible.
