old leather rocker

Old leather wing back rocking chair.  Quite massive.  Looks like somemething out of an old West hunting lodge or saloon. Horse hair batting on arms, cotton? in cushions. Coil spring seat.  Found in basement of father-in-law's house during estate clean up.  Wife wants to restore it as a DIY project to honor her father.  I just want to get some idea of what it is, where and when its from before we start tearing it apart and destroy the chair that Teddy Roosevelt might have had in his log cabin!
