Heres yet another odd sized stone that I believe is Thuringian. The measurments are 5 13/16" L X 3 3/8" W X 7/16" thick. I have put it next to my "Celebrated Thuringian" hone. This stone is a little bit harder to slurry and is dark blue color, it slurries the same color as the celebrated hone in color but is a slightly harder stone( very good finisher). I suppose Thuringian hones or stones were cut in different sizes is my point, what is your opinion?
