Thread: Help needed to identify hone

I'm new to the Straight Razor Place so this is my first post. I looking for help to identify a hone I recently purchased on ebay. It was advertised as a Thuringian, however I suspect this is incorrect as I don't think it has the right colour and is not soft enough. It came in a wooden paddle and is approx 150mm x 25mm and dark brown in colour. I have lapped it on one side and the colour of the slurry produced doing this was a choclate brown, initially I thought this was due to it been oil soaked however after lapping for a couple of hours the colour did not vary. The stone is very hard and fine to touch, and except for a few white blemishes and one orange spot is very consistant in it's colour. Any help from you very knowledgeable people would be gratefully received.
