Hone ID please.

[alpla444]

I know its hard to ID vintage hones from photo's but here goes. I only paid £1 for it so no loss.

Its size is more or less 1" X 2" X 8"

I have pics showing mainly dry, with slurry and a wet pic.
The Stone feels quite smooth (I have NOT had chance to get a razor onto it yet, I will later on and post my findings. I feel its NOT a finishing hone, as I have a vintage Thuringian and it does not feel as smooth as that.
Any input is appreciated thanks in advance.
