Identification on stones found today

[Dafonz6987]

Cruised over the antiques mall with the wife today and found a vender that had quite a bit of straight razor supplies. The vender wasn't currently there but he had these stones, a pike swaty stone which I searched and people were saying it's about a 15k hone (of course if you know more please let me know!) another stone with the satis factory co. Written on it. This stone feels a little more abrasive then the pike swaty. Then the last stone is what I would believe is a natural stone judging on the coloring, there was another stone that was there which I didn't purchase but it at least the box said Arkansas natural but I'm not sure if this is the same as this stone had no kind of writing on it but it almost feels as smooth as the pike swaty and my shapton 15k. Obviously I won't know for sure on these things for sure until I hone and check the progression under 100x magnification but if someone could give me a head start with some info I would appreciate it.

as always thanks for taking the time to read this and reply the communities help is always appreciated!
