I think it's another Thuringian
Out in an antique shop today, saw this little guy in a tool box (marked as "tool"). It reminded me of my German Water Stone in size and feel so I bought it. Plus the price was so low it was pretty much no risk. Check out the pictures and let me know what you think, yes I know it's really hard to tell without a box or labels but I'm fairly certain it's a very light colored Thuringian. It is the stone across the bottom, the stone at the 2 o' clock is my labeled thuringian, and the stone to the 11 o' clock is my other recent acquisition a wasserabziehstein (water stone). In person, the Wasser is much darker and bluish, the Thuri is green, and the new unknown is much lighter green.
