I would get that tape off of there. It will either pull the finish off or leave a sticky mess when it is pulled off if it is left there very long. If it leaves a sticky mess, I would remove it with boiled linseed oil or some other stock oil. A gun sock would be much better to protect the rifles.
Hard to tell about the 71 but the 1895 is not original. There were no second model 95's made with a pistol grip. The lever has been bent and the stock has been replaced. The lower tang has been modified to fit the pistol grip. I bet it is also reblued. I don't know what its worth but it isn't a collector.
